Hello there,     We have one of the spark job (1.4.1 Version) that runs some basic HIVE SQL Select/Insert queries. Sometimes the driver kills all the allocated executors when the new stage gets started and the application hangs/idle for longer time (job in running status). If I bring down the worker node where the driver is running then a new driver is getting started and allocating all the executors. What is the reason for executors getting killed by the driver. No errors on the logs.   Thanks @Spark @hadoop2 @Hadoop @Apache Spark ... View more
