Vinod K V commented on HADOOP-5349:
-----------------------------------
When the size required is unknown, LocalDirAllocator selects one target disk in
a round-robin fashion. Before returning this path, it tries to create the path.
If the selected disk turns about to be bad, then
LocalDirAllocator.getLocalPathForWrite fails with a DiskCheckerException. The
fix for this is to make getLocalPathWrite to try other disks till it finds one,
similar to the case when required size of the path is known.
> When the size required for a path is -1,
> LocalDirAllocator.getLocalPathForWrite fails with a DiskCheckerException when
> the disk it selects is bad.
