Subject [jira] [Created] (HDFS-5024) Make createCommitBlockSynchronization idempotent
Date Tue, 23 Jul 2013 22:06:49 GMT
Arpit Agarwal created HDFS-5024:
-----------------------------------

             Summary: Make createCommitBlockSynchronization idempotent
                 Key: HDFS-5024
                 URL: https://issues.apache.org/jira/browse/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.
