Description

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.
