Summary: Support to alter table properties in
HBaseTimelineSchemaCreator
Key: YARN-9465
URL: https://issues.apache.org/jira/browse/YARN-9465
Project: Hadoop YARN
Issue Type: Sub-task
Components: timelinereader
Affects Versions: 3.2.0
Reporter: Tarun Parimi
Assignee: Tarun Parimi
HBaseTimelineSchemaCreator currently only creates tables if they don't exist.
Only creating hbase tables without altering is the desired behavior for most of
the use cases.
However, in certain scenarios we might need to alter tables.
For example after upgrade, we might need to point to a new coprocessor jar in
yarn.timeline-service.hbase.coprocessor.jar.hdfs.location .
A user might also want to change the ttl of the tables afterwards to control
the data retention. Currently user has to manually find the tables related to
atsv2 and alter them with hbase shell, which is not straightforward.
To support such scenarios, it will be useful to have an option to alter table
if required in HBaseTimelineSchemaCreator.
