Varun Vasudev commented on YARN-4731:
-------------------------------------
The signal container exception and the container initalization error can be
ignored. The signal container exception is due to the fact that we call signal
container as part of the container cleanup and the container initialization
error is due to the MR AM killing the last reducer.
