for the past few month we used the ambari with few servers.
I am trying to improve the time it take from submiting the job, to the time the jobs actualy starts\
In the current setup we have 4 computers with total of 64 executors
when the job is accepted in the server it take aprox 35 seconds to initialize all exectutors and start our process, where i can find the reason and is it posibble to improve\optimize the flow ?
can i keep the executor alive ? most of them time (99.99 % of the cases ) it the cpu/ram is not changed upon submited job
we based on HDP-184.108.40.206
