Big Data Cloud Console: Settings Page

The Big Data Cloud Console: Settings page displays information for managing resource queues configurations, notebook server restart, and interpreter settings for the Big Data Cloud cluster.

What You Can Do from the Big Data Cloud Console: Settings Page

Use the Settings page to perform tasks described in the following topics:

What You See in the Navigation Area

Element Description
User name menu icon

User menu providing access to the API Catalog for Big Data Cloud, Help for this page, and About information with details about the console.

Overview

Click to go to the Overview page.

Jobs

Click to go to the Jobs page.

Notebook

Click to go to the Notebook page.

Data Stores

Click to go to the Data Stores page.

Status

Click to see information about components and services running on Oracle Big Data Cloud clusters and nodes and their associated state.

What You See in the Queues Region

Element Description
New Queue Icon

Click to create a new Queue.

Preemption

Displays if Preemption is enabled or disabled for queues.

  • Preemption Off: Indicates that Jobs can't consume more resources than a specific queue allows. This will lead to potentially lower cluster utilization.

  • Preemption On: Indicates that Jobs can consume more resources than a queue allows, but could lose those resources when another job comes in that has priority for those resources.

    If preemption is on, jobs submitted to a particular queue do not have to wait because jobs of some other queue have taken up the available cluster capacity. If preemption is on, and if the cluster is unused, then jobs from any queue can utilize 100% of the cluster capacity. This will lead to better cluster utilization.

Queue Name

The name used to identify the resource queue.

Capacity (%)

The guaranteed capacity of each queue which specifies the percentage of cluster resources that are available for applications submitted to the queue.

Max Capacity (%)

The maximum capacity of the queue. Max Capacity is automatically sets to 100% when preemption is enabled. Otherwise it is the same as Capacity.

Total Queues Capacity

The total capacity of all queues put together.

What You See in the Credentials Region

Element Description

Cloud Storage

Allows you to reset the Oracle Cloud Infrastructure Object Storage Classic password associated with the cluster.

This password is associated with the account used during provisioning of the cluster. It should only be changed if the Oracle Cloud Infrastructure Object Storage Classic password has been changed outside of the Big Data Cloud service.

  • Password: Enter the new Oracle Cloud Infrastructure Object Storage Classic password that you want to save for this cluster.

  • Confirm Password: Re-enter the new Oracle Cloud Infrastructure Object Storage Classic password that you want to save for this cluster.

  • Save: Click to save the new password.

System Credentials

System Credentials are secrets required by the platform (including the Oracle Cloud Infrastructure Object Storage Classic password) which are updated through the system credential User Interface and/or the REST API.

Any credentials held within the system credential store can be updated, but they cannot be deleted.

Credentials stored in the System and User Credential store are accessible to applications during runtime through the Apache Hadoop org.apache.hadoop.conf.Configuration.getPassword() API.

User Credentials

For a cluster, User Credentials allows you to store a user or application specific credentials in the credential store.

  • Refresh icon: Click to reload the user credentials.

  • New credential icon: Click to add a new credential.

  • Key: A unique identifier for the credential.

  • Value: The new user or application password that you want to save for the cluster.

  • Save: Click to save the new password.

  • Delete icon: Click to delete the credential.

What You See in the JDBC URLs Region

Element Description

Spark Thrift URL

URL for the Spark Thrift Server. The URLs differ depending on whether a cluster uses Basic authentication or uses IDCS for authentication. For information about cluster authentication, see Use Identity Cloud Service for Cluster Authentication.

Basic authentication cluster

jdbc:hive2://ip_address:1080/default;ssl=true;sslTrustStore=path_to_truststore;trustStorePassword=truststore_password?hive.server2.transport.mode=http;hive.server2.thrift.http.path=cliservice

Where:

  • ip_address is the IP address of the desired endpoint

  • path_to_truststore is the absolute path to the Java Trust Store that holds the certificate

  • truststore_password is the password used with the trust store

IDCS-enabled cluster

jdbc:hive2://cluster_name-load_balancing_server_URI/default;ssl=true?hive.server2.transport.mode=http;hive.server2.thrift.http.path=cliservice

Where:

  • cluster_name is the name of the cluster

  • load_balancing_server_URI is the URI assigned to the cluster by the load balancing service

For more information about Thrift access, see About Accessing Thrift.

Hive Thrift URL

URL for the Hive Thrift Server. The URL is different depending on whether you have a Basic authentication cluster or an IDCS-enabled cluster.

Basic authentication cluster

jdbc:hive2://ip_address:1080/default;ssl=true;sslTrustStore=path_to_truststore;trustStorePassword=truststore_password?hive.server2.transport.mode=http;hive.server2.thrift.http.path=hs2service

Where:

  • ip_address is the IP address of the desired endpoint

  • path_to_truststore is the absolute path to the Java Trust Store that holds the certificate

  • truststore_password is the password used with the trust store

IDCS-enabled cluster

jdbc:hive2://cluster_name-load_balancing_server_URI/default;ssl=true?hive.server2.transport.mode=http;hive.server2.thrift.http.path=hs2service

Where:

  • cluster_name is the name of the cluster

  • load_balancing_server_URI is the URI assigned to the cluster by the load balancing service

For more information about Thrift access, see About Accessing Thrift.

What You See in the Notebook Region

Element Description
Restart icon to restart a notebook.

Click to restart the notebook server when the data is cached.

Apart from restarting Notebooks, you can also manage interpreter settings for Notebooks from this region.
