Description

Currently the TimelineSchemaCreator has a concrete implementation for creating Timeline Schema's only for HBase, Hence creating this JIRA for supporting multiple back-ends that ATSv2 can support.

Usage:

       Add the following property in yarn-site.xml

<!-- config required for specifying the TimelineSchemaCreator class for ATSv2-->
<property>
 <name>yarn.timeline-service.schema-creator.class
 </name>
 <value>YOUR_TIMELINE_SCHEMA_CREATOR_CLASS</value> <!-- Default is org.apache.hadoop.yarn.server.timelineservice.storage.HBaseTimelineSchemaCreator-->
</property>

    The Command needed to run the TimelineSchemaCreator need not be changed i.e the below existing command can be used irrespective of the backend configured.

bin/hadoop org.apache.hadoop.yarn.server.timelineservice.storage.TimelineSchemaCreator -create
