This chapter describes the utilities available on Oracle Big Data Appliance. Most of the utilities are for monitoring the health of the hardware and the network.
Checks the health of a CDH cluster, including the software, hardware, and network, and logs the results in a file in the /tmp
directory.
To also run the CDH cluster health checks, enter the Cloudera Manager admin
password in response to the prompt. If you do not enter the password, then these checks are skipped.
Syntax
bdacheckcluster
Notes
If the cluster is protected by Kerberos authentication, then you must obtain a ticket for the hdfs
user before running bdacheckcluster
.
Example
This example shows the output from the utility:
# bdacheckcluster INFO: Logging results to /tmp/bdacheckcluster_1373393815/ Enter CM admin password to enable check for CM services and hosts Press ENTER twice to skip CM services and hosts checks Enter password: password Enter password again: password SUCCESS: Mammoth configuration file is valid.

Checks the InfiniBand cabling between the servers and switches of a single rack, when entered with no options.
Run this command after connecting as root
to any server.
Syntax
bdacheckib [parameter]
Parameters
The same as running without options except that the network must still be configured with the factory default settings. You can use this option as soon as Oracle Big Data Appliance arrives at the site, even before the switches are configured.
Verifies that the InfiniBand switch-to-switch cabling among multiple racks is correct. To create json_file, see the -g
option.
Generates a sample JSON file named sample-multi-rack.json
. Use this file as an example of the format required by the -m
option.
Usage Notes
The network must be configured with custom settings as described by /opt/oracle/bda/network.json
.
Examples
This example checks the switch-to-server InfiniBand cables:
[root@node01 network]# bdacheckib
LINK bda1sw-ib3.15A ... bda1node02.HCA-1.2 UP
LINK bda1sw-ib3.15B ... bda1node01.HCA-1.2 UP
LINK bda1sw-ib3.14A ... bda1node04.HCA-1.2 UP
LINK bda1sw-ib3.14B ... bda1node03.HCA-1.2 UP
.
.
.
The next example generates the JSON file and shows the output.
[root@bda1node01 bda]# bdacheckib -g [root@bda1node01 bda]# cat sample-multi-rack.json # This json multirack spec is generated. The array elements are sorted # alphabetically. A properly arranged json spec representing racks from left to right # can be used as input to bdacheckib (bdacheckib -m multi-rack.json) # Note commas separating rack elements are optional. [ {"SPINE_NAME": "bda1sw-ib1", "LEAF1_NAME": "bda1sw-ib2", "LEAF2_NAME": "bda1sw-ib3"} {"SPINE_NAME": "bda2sw-ib1", "LEAF1_NAME": "bda2sw-ib2", "LEAF2_NAME": "bda2sw-ib3"} {"SPINE_NAME": "dm01sw-ib1", "LEAF1_NAME": "dm01sw-ib2", "LEAF2_NAME": "dm01sw-ib3"}
The final example checks all the racks on the InfiniBand network using the edited JSON file created in the previous example:
# bdacheckib -m sample-multi-rack.json

The Oracle Big Data Appliance Command-Line Interface (bdacli
) queries various configuration files to return information about the rack, cluster, server, InfiniBand network, and software patches.
The bdacli
utility also adds and removes patches and optional services. It can migrate critical services between critical nodes, and add and remove servers from a cluster.
The bdacli
utility displays usage information if no parameters are included on the command line or the values are undefined.
Syntax
bdacli action [parameters]
Actions
Displays general usage information for bdacli, a list of actions, and a list of supported parameters for the getinfo
action.

Enables you to administer the nodes in a cluster in response to a failing server.Table 11-1 describes the parameters.
Table 11-1 bdacli admin_cluster parameters
Parameter | Description |
---|---|
|
Removes the specified node from the cluster and decommissions the server in Cloudera Manager. It also updates the Mammoth files. You can decommission a failing, noncritical node. Note that critical services on the node must be moved first. This parameter is for temporarily removing a node from a cluster for maintenance and is not a method to delete a node from a cluster. |
|
Removes the node from the list of decommissioned nodes, and recommissions the server in Cloudera Manager. Use this command after decommissioning and repairing a failing server. |
|
Moves the services from a critical node to a noncritical node, and decommissions the failing server in Cloudera Manager. You specify the name of the failing critical node, and the utility selects the noncritical node for the migration. When migration is complete, the new node has all of the functionality of the original critical node. You can only migrate a critical node, and should do so only when it is failing. Note: In Oracle Big Data Appliance 4.9, migration does not support Oracle Big Data SQL. If Oracle Big Data SQL is installed, disable it first, run the migration, and then re-enable Oracle Big Data SQL.Use |
|
Restores a server to the cluster as a noncritical node, and recommissions the server in Cloudera Manager. Use this command after migrating the services of a critical node and repairing the failing server. |
Enables or disables an optional software component on Oracle Big Data Appliance. You must log in as root
to use enable

Disable existing eCryptfs encryption. |
|
HDFS Transparent Encryption on the cluster. Respond Yes or No to a prompt to set up Key Trustee Servers on the BDA. If you respond No, you are further prompted for the addresses of the Active and Passive Key Trustee Servers, as well as the Key Trustee organization and authorization code. If you respond Yes, the Key Trustee Servers are set up on Oracle Big Data Appliance in a predetermined configuration. Kerberos is required. See After the initial configuration, starting/stopping the KMS/KTS servers can be done only through Cloudera Manager. Mammoth does not have direct access to edge nodes and therefore cannot set up or detect KMS services on these nodes. Customers can set up KMS services on edge nodes themselves. These must exist same cluster as the services that require access to the Key Trustee Servers. See Also:
|
|
Active Directory Kerberos. Also prompts the user to choose whether or not to enable the features Encrypt Hadoop Services and Encrypt HDFS Data Transport. The Note that there are important preliminary steps. See MOS (My Oracle Support) documents 2013585.1 and 2029378.1. |
|
MIT Kerberos. Also prompts the user to choose whether or not to enable the features Encrypt Hadoop Services and Encrypt HDFS Data Transport. The disable option disables these services as well as MIT Kerberos. This parameter does not control Active Directory Kerberos. See |
|
HTTPS for Cloudera Manager, Hue, and Oozie. There is no disable option. Kerberos is required. |
|
Encryption of HDFS data transport between DataNodes and clients, and among DataNodes. Kerberos is required. Applies to HDFS data only. |
|
HTTPS encryption and Kerberos authentication for HDFS and YARN, also enables encrypted web shuffling for YARN. Data spills to non-HFDS disk storage from Spark shuffle, MapReduce intermediate files, map and reduce operations, and Impala SQL are also encrypted. Basically this option encrypts all network traffic except HDFS data transport. Kerberos is required. |
|
Apache Sentry authorization |
Note:
If HDFS Transparent Encryption is disabled, data stored in the HDFS Transparent Encryption zones in the cluster will remain encrypted and therefore inaccessible. To restore access to the data, re-enable HDFS Transparent Encryption using the same key provider.

Syntax
bdaredoclientnet
Usage Notes
Log in to server 1 and change to the /opt/oracle/bda/network
directory to run this utility.
You must run this utility after changing the number of 10 GbE connections to a Sun Network QDR InfiniBand Gateway switch. See "Changing the Number of Connections to a Gateway Switch".
The bdaredoclientnet
utility performs the following subset of tasks done by the networksetup-two
script during the initial configuration of Oracle Big Data Appliance:
Verifies that the administrative network is working, the InfiniBand cabling is correct, and the InfiniBand switches are available
Determines how many 10 GbE connections are available and connects them to the InfiniBand Gateway switches
Deletes all VNICs and re-creates them
Connects to each server and updates the configuration files
Restarts the client network and verifies that it can connect to each server using the newly configured client network

Turns off swapping by the operating system.
Syntax
bdaswapoff
Usage Notes
The bdaswapoff
utility disables both swap partitions on a server, which disables all swapping by the operating system. This state persists when the server restarts; you must run bdaswapon
to restore swapping. Swapping is turned off by default to improve performance and to allow high availability if a disk fails.
Use bdaswapoff
instead of the Linux swapoff
utility.

Example
This example turns off swapping:
# bdaswapoff #
Turns on paging and swapping by the operating system.
Syntax
bdaswapon
Usage Notes
Swapping is turned off by default to improve performance and the ability to recover from disk failure.
Use bdaswapon
instead of the Linux swapon
utility.

Updates the firmware of a particular component of a server, such as a replacement disk drive.
Syntax
bdaupdatefw parameter
Parameters
Updates the LSI disk firmware for the specified disk (N). Each server has 12 disks, which are numbered from 0 to 11.
Specifies the file path to the firmware. If the path is omitted, then bdaupdatefw
uses the default firmware for the specified component from /opt/oracle/bda/firmware
.
Displays syntax and usage information for bdaupdatefw
.
Updates the Oracle ILOM firmware.
Updates the LSI disk controller firmware.
Updates the firmware for the Mellanox host channel adapter (InfiniBand card).
Usage
This utility is typically run by Oracle field engineers when installing or replacing hardware components, which may not be factory-installed with a supported firmware version. During a software installation, Mammoth copies the currently supported firmware to Oracle Big Data Appliance. The bdaupdatefw
command uses those files when they are needed to update the firmware of a server component.
You can update one firmware package in a single command. Thus, you can specify only one of the following parameters: -d
, -i
, -l
, or -m
.
Caution:
Only use the firmware provided in a Mammoth bundle. Do not attempt to install firmware downloaded from a third-party site. Doing so may result in the loss of warranty and support.
Examples
This example shows the output from a command to update the Oracle ILOM firmware. To perform the update, you must execute the ipmiflash
command provided in the output.
