Are you trying to fetch a large result to your client using the collect() method? Best, Fabian 2018-05-02 0:38 GMT+02:00 Chan, Regina <regina.c...@gs.com<mailto:regina.c...@gs.com>>: Hi, I’m running a single TM with the following params -yn 1 -ys 2 -yjm 36864 -ytm 24576 -yD akka.framesize=2097152000b I keep repeatedly getting this error where I’m losing connection to the JobManager. It’s not clear why, it seems like the job is finishing up until the Datasink but the JobManager is lost before that completes. I’ve attached the jobmanager logs.
