Christian Kunz commented on HADOOP-2227:
----------------------------------------
I have to correct my previous comment, as the map output gets merged into a
single file, i.e. free space should not be added up, but when one of the disks
has enough space for a task, then TaskTracker.enoughFreeSpace should return
true.
> wrong usage of mapred.local.dir.minspacestart

> Key: HADOOP-2227
> URL: https://issues.apache.org/jira/browse/HADOOP-2227
> Project: Hadoop
> Issue Type: Bug
> Components: mapred
> Affects Versions: 0.15.1
> Reporter: Christian Kunz
> Priority: Critical
>
> As I understand it, mapred.local.dir.minspacestart should be used to specify
> that a map or reduce task requires a minimum disk space to be executed. When
> several disks are available, and mapred.local.dir lists all of them, then the
> free space should be added up. But TaskTracker.enoughFreeSpace returns false
> whenever one of the disks listed in mapred.local.dir has less than the space
> specified by mapred.local.dir.minspacestart.
