I see, that makes sense, but in that case we need to do a couple more
things to make this complete:
1) We should have a max limit of broken dirs we tolerate, after which we'd
throw an error.
2) spark.local.dir is used to specify a list of directories that the
DiskStore puts data in. You need to modify the DiskStore to allow skipping some
of them, or else there will still be problems.
If you don't have time to look through the rest of the code to do this,
then please just add your discussion above to the JIRA and other people will
get to it later.
