This section describes changes to Hadoop distribution configuration.
Hadoop Distribution Configuration
Effective in version 10.2.1, you configure the Hadoop distribution in cluster configuration properties.
The Distribution Name and Distribution Version properties are populated when you import a cluster configuration from the cluster. You can edit the distribution version after you finish the import process.
Previously, the Hadoop distribution was identified by the path to the distribution directory on the machine that hosts the Data Integration Service.
Effective in version 10.2.1, the following property is removed from the Data Integration Service properties:
Data Integration Service Hadoop Distribution Directory
For more information about the Distribution Name and Distribution Version properties, see the
Big Data Management 10.2.1 Administration Guide.
Effective in version 10.2.1, it is no longer necessary to configure Data Integration Service process properties for the domain when you use Big Data Management with MapR. Big Data Management supports Kerberos authentication with no user action necessary.
Previously, you configured JVM Option properties in the Data Integration Service custom properties, as well as environment variables, to enable support for Kerberos authentication.
For more information about integrating the domain with a MapR cluster, see the
Big Data Management 10.2.1 Hadoop Integration Guide.
