I carried out PiEstimator job at Hadoop cluster which applied YARN-321.
After the job end and when I accessed Web UI of HistoryServer, it displayed
"500". And HistoryServer daemon log was output as follows.

I confirmed that there was container which was not finished from
ApplicationHistory file.
In ResourceManager daemon log, ResourceManager reserved this container, but did
not allocate it.
Therefore, about a container which is not allocated, it is necessary to change
how to handle in ApplicationHistory.
