Ravi Gummadi commented on MAPREDUCE-2957:
-----------------------------------------
+1 to avoid calling TaskTracker.initialize() if there are no good local dirs.
Even with this patch, i.e. though State.DENIED is returned by offerService()
when DiskCheckerException is seen, initialize() is getting called once more and
is getting DiskCheckerException from TT.initialize() ->
DiskChecker.checkLocalDirs(). This behavior is similar to what was happening
without this patch. This needs to be improved somehow and we need to avoid the
call to TT.initialize() in this case.
> The TT should not re-init if it has no good local dirs
