Hemanth Yamijala commented on MAPREDUCE-4649:
---------------------------------------------
On this topic, what is the purpose of mr-jobhistory-daemon ? Is it just for
starting the history server ? If yes, then should we really pass in the command
to start, like:
mr-jobhistory-daemon.sh start historyserver
Can't it just be:
mr-jobhistory-daemon.sh start
and 'historyserver' is passed internally ?
> mr-jobhistory-daemon.sh needs to be updated post YARN-1
