Time taken for launching Application Master
Hi,
I am seeing that from the time ApplicationMaster is sumitted by my
Client to the ASM part of RM, it is taking around 7 seconds for AM to get
started. Is there a way to reduce that time, I mean to speed it up?
Thanks,
Kishore

Check your node manager logs to understand the bottleneck first. When we
had a similar issue on recent version of hadoop, which includes fix for
MAPREDUCE-4068: we rearranged our job jar file to reduce time spent on
'expanding' the job jar file by the node manager(s).
