Tom White updated MAPREDUCE-4463:
---------------------------------
Attachment: MAPREDUCE-4463.patch
Thanks for reviewing the patch Mayank.
I don't think checking for {{dfs.isClusterUp()}} in the test is needed, and in
fact it will return false if the cluster is in safemode, in which case we would
still want to call shutdown. Other tests just check that the instance variable
is non-null.
I've made a change to make the test more robust and also to guard against a
race condition where the tasktracker reinitializes and old tasks that are still
running interfere with new TIPs in recovered jobs.
