-----------------------------------
Summary: Make createCommitBlockSynchronization idempotent
Key: HDFS-5024

Project: Hadoop HDFS
Issue Type: Bug
Components: namenode
Affects Versions: 3.0.0, 2.1.0-beta
Reporter: Arpit Agarwal
Assignee: Arpit Agarwal
commitBlockSynchronization is not idempotent (repeated invocations with the
same arguments will throw an exception). By making it Idempotent we can remove
the requirement to track invocations using the retry cache.
