Subject [jira] [Created] (HADOOP-8765) LocalDirAllocator.ifExists API is broken and unused
Date Wed, 05 Sep 2012 04:49:07 GMT
Hemanth Yamijala created HADOOP-8765:
----------------------------------------

             Summary: LocalDirAllocator.ifExists API is broken and unused
                 Key: HADOOP-8765
                 URL: https://issues.apache.org/jira/browse/HADOOP-8765
             Project: Hadoop Common
          Issue Type: Bug
          Components: fs
            Reporter: Hemanth Yamijala
            Assignee: Hemanth Yamijala
            Priority: Minor


LocalDirAllocator.ifExists calls AllocatorPerContext.ifExists, which accesses the localDirsPath
variable that is uninitialised. Hence, any code that uses this API is likely to fail with
a NullPointerException.

However, this API is currently not used anywhere else in trunk. The earlier usage was in IsolationRunner,
that has since been removed via MAPREDUCE-2606.

Hence, we could remove this API for trunk, and if required, fix it for the 1.x branch.
