Nodes, OCPUs, Memory, and Storage |
Summary of resources being used:
|
Status |
Status of the Oracle Big Data Cloud cluster. |
User Name |
Administrative user name. For clusters that use Basic authentication, the administrative user name and password are used to access the cluster console, REST APIs, and Apache Ambari. For clusters that use IDCS for authentication, the administrative user name and password are used only to access Ambari. Cluster access is managed through IDCS. |
Compute Shape |
The shape of all the nodes in the Oracle Big Data Cloud cluster. |
Spark Thrift Server |
The URL for JDBC connection to Thrift. There are two relevant service URLs, one for Spark Thrift Server and one for Hive Thrift Server. The URLs differ depending on whether you have a Basic authentication cluster or an IDCS-enabled cluster. For IDCS-enabled clusters, interactions are routed through the load balancing server instead of going directly to the cluster, and that difference is reflected in the URL.

For more information about Thrift access, see About Accessing Thrift. |
Version |
Version of Oracle Big Data Cloud configured on the cluster. |
Ambari Server Host |
The IP address of the server hosting Ambari. |
Deployment Profile |
