> I'm encountering an issue with the Mapreduce HistoryServer processing the
> history files for large jobs. This has come up several times with for jobs
> with around 60000 total tasks. When the HistoryServer loads the .jhist file
> from HDFS for a job of that size (which is usually around 500 Mb), the
> HistoryServer's CPU usage spiked and the UI became unresponsive. After about
> 10 minutes I restarted the HistoryServer and it was behaving normally again.
> The cluster is running CDH 5.3 (2.5.0-cdh5.3.0). I've attached the output of
> jstack from a time this was occurring.
