> Key: MAPREDUCE-3011
> URL: https://issues.apache.org/jira/browse/MAPREDUCE-3011
> Project: Hadoop Map/Reduce
> Issue Type: Sub-task
> Components: tasktracker
> Affects Versions: 0.20.204.0
> Reporter: Eli Collins
>
> Per HADOOP-7551 the TT does not remove bad mapred.local.dirs from the conf so
> after a single disk failure *every* call to get a local path for reading or
> writing results in a disk check of *all* configured local dirs. After
> detecting that a local dir is bad we should remove it from the conf so that
> we don't repeatedly perform this expensive operation.
