Eli Collins updated MAPREDUCE-2928:
-----------------------------------
Attachment: mapreduce-2928-3.patch
@Ravi, good suggestion - updated patch attached.
bq. May be in a separate JIRA, we can add LocalStorage.checkBadLocalDirs() call
to TT.initialize() that can do disk-health-check of bad local dirs and add dirs
to the good local dirs list if they become good.
Sounds good. Since transient disk failures may cause a file system to become
read-only (causing permanent failures) sometimes re-mounting is sufficient to
recover in which case it makes sense to re-enable faulty disks w/o TT restart.
