> Whenever OOM Error is thown, {{YarnUncaughtExceptionHandler}} will call
> {{ExitUtil.halt(-1)}}.But while halting, OOM might occur which is not
> handled.
> We came across a scenario where in when we submit mapreduce application ,OOM
> error occured in {{committerEventProcessor}} and then AM did not halt and did
> not log the following.Finally AM got hang since it's not thrown to main
> thread.
> {code}LOG.info("Halt with status " + status + " Message: " + msg);{code}
> *org.apache.hadoop.util.ExitUtil.halt(int, String)*
> {code}
> public static void halt(int status, String msg) throws HaltException {
> LOG.info("Halt with status " + status + " Message: " + msg);
> if (systemHaltDisabled) {
> HaltException ee = new HaltException(status, msg);
> LOG.fatal("Halt called", ee);
> if (null == firstHaltException) {
> firstHaltException = ee;
> }
> throw ee;
> }
> Runtime.getRuntime().halt(status);
> }
