Chinna Rao Lalam commented on HIVE-2017:
----------------------------------------
taskCleanup() is calling System.exit(9) it will exit from JVM. Here instead of
calling
System.exit(9) we need to kill the map-reduce & non MR processes
> Driver.execute() should maintaining SessionState in case of runtime errors

> Here's a snippet from Driver.execute():
> {code}
> // TODO: This error messaging is not very informative. Fix that.
> errorMessage = "FAILED: Execution Error, return code " + exitVal
> + " from "
> + tsk.getClass().getName();
> SQLState = "08S01";
> console.printError(errorMessage);
> if (running.size() != 0) {
> taskCleanup();
> }
> return 9;
> {code}
> I simply returned in case of runtime errors without maintaining SessionState.
> It could cause resource leak mentioned in HIVE-1959.
