Subject Re: default capacity scheduler only one job in running status
Date Wed, 27 Nov 2013 01:29:55 GMT
yes yarn.scheduler.capacity.maximum-am-resource-percent option is a limit,
i increase the value from 0.1 to 0.8 but ,it can still allow 2 job run
parallel,if i laugh
third job ,it still need wait,why? the whole cluster only can run 2 job
parallel?
