How to start historyserver on all nodes automatically?
Hi all,
I have enabled log aggregation and want to track task logs on hdfs. I need
to start historyserver vie mr-jobhistory-daemon.sh start historyserver on
all nodes. Is there any way to run historyserver automatically when yarn
starts?

Hi,
You do not need to run an MR HistoryServer on all nodes. If you want
"start-yarn.sh" to cover the history server startup you can also
inject the command at its end.
