Thanks for the reply, our scenario was a failure test to see if the job would 
recover on its own after killing a TM.
It turns out that the job gets a SIGNAL 15 hang during the switch from 
DEPLOYING to INITIALIZING. Because zk's ha appears to restart repeatedly

My confusion
1. why does it receive SIGNAL 15
2. is it because of some configuration? (e.g. deploy timeout causing kill?)

Hi,

 

One possible direction is to check your YARN log or TM log to see if the YARN 
RM kills the TM for some reason(e.g. physical memory is over limit) and as a 
result, the JM will try to recover the TM repeatedly according to your restart 
strategy.

The snippet of JM logs you provide is usually not the root cause.

 

Best,
Biao Geng
