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.
