Charles Butterfield commented on HADOOP-5247:
---------------------------------------------
I'm running 0.20.2 and have just gotten an NPE calling
NetworkedJob.isComplete(), while the DFS is under heavy stress (multiple node
removed from service).
This seems to be exactly the case that Vinod identified last year. I could not
find any open ticket. Should this ticket be reopened? Please advice.
