Subject [jira] [Commented] (YARN-7053) Move curator transaction support to ZKCuratorManager
Date Mon, 21 Aug 2017 22:41:00 GMT

Jonathan Hung commented on YARN-7053:
-------------------------------------

Thanks [~subru] for the review. Added a ZKCuratorManager test.

Regarding ZookeeperFederationStateStore transactions, I didn't see any existing transactions
in this class that could be refactored. And the only place adding transactions seemed applicable
was in the {{put(String znode, byte[] data, boolean update)}} method. Did you want to change
the {{put}} logic as part of this ticket?

> HADOOP-14741 moves curator functionality to ZKCuratorManager. ZKRMStateStore has some
curator transaction support which can be reused, so this can be moved to ZKCuratorManager
as well.
