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.
