https://issues.apache.org/jira/browse/SPARK-4012 This patch is a resubmission for https://github.com/apache/spark/pull/2864 What I am proposing in this patch is that ***when the exception is thrown from an infinite loop, we should stop the SparkContext, instead of let JVM throws exception forever*** So, in the infinite loops where we originally wrapped with a ` logUncaughtExceptions`, I changed to `tryOrStopSparkContext`, so that the Spark component is stopped Early stopped JVM process is helpful for HA scheme design, for example, The user has a script checking the existence of the pid of the Spark Streaming driver for monitoring the availability; with the code before this patch, the JVM process is still available but not functional when the exceptions are thrown andrewor14, srowen , mind taking further consideration about the change?
