[jira] [Updated] (HADOOP-7900) LocalDirAllocator confChanged()
accesses conf.get() twice
[ https://issues.apache.org/jira/browse/HADOOP-7900?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Ravi Gummadi updated HADOOP-7900:
---------------------------------
Component/s: fs
Description: 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.
Environment: (was: mr)
