SPARK_JAVA_OPTS="$SPARK_JAVA_OPTS -Dspark.akka.askTimeout=300 -Dspark.ui.retainedStages=1000 -Dspark.eventLog.enabled=true -Dspark.eventLog.dir=hdfs://sparkcluster/user/spark_history_logs -Dspark.shuffle.spill=false -Dspark.shuffle.manager=hash -Dspark.yarn.max.executor.failures=99999 -Dspark.worker.timeout=300" I just find log like this: INFO ClientCnxn: Client session timed out, have not heard from server in 40015ms for sessionid 0x351c416297a145a, closing socket connection and attempting reconnect Before spark2 master process shut down. I don’t see any zookeeper timeout setting .
