Subject [jira] [Commented] (HADOOP-8765) LocalDirAllocator.ifExists API is broken and unused
Date Wed, 05 Sep 2012 05:12:07 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-8765?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13448487#comment-13448487
] 

Hemanth Yamijala commented on HADOOP-8765:
------------------------------------------

BTW, all other calls to LocalDirAllocator first call AllocatorPerContext.confChanged, that
is responsible for initialising the localDirsPath. Inserting that call fixes the NullPointerException.

> 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.
