>
> Key: HADOOP-7900
> URL: https://issues.apache.org/jira/browse/HADOOP-7900
> Project: Hadoop Common
> Issue Type: Bug
> Components: fs
> Affects Versions: 0.24.0, 0.23.1
> Reporter: Ravi Gummadi
> Assignee: Ravi Gummadi
> Fix For: 0.24.0, 0.23.3
>
> Attachments: HADOOP-7900.patch
>
>
> LocalDirAllocator.AllocatorPerContext.confChanged() accesses conf.get() twice
> unnecessarily. The 2 calls can give 2 different values, which can lead to
> issues because the first call's return value is saved in savedLocalDirs and
> is used for comparison in the next call to confChanged() method --- So the
> comparison is wrong.
