--------------------------------

Can we use Thread.setUncaughtExceptionHandler() to resolve this?

> up to  hadoop 0.18.3 org.apache.hadoop.mapred.JobShell ensured that 'hadoop jar' returns non-zero exit code when the job fails.
> This is no longer true after moving this to org.apache.hadoop.util.RunJar.
> Pipes jobs submitted through cli never returned proper exit code.
> The main methods in org.apache.hadoop.util.RunJar. and org.apache.hadoop.mapred.pipes.Submitter should be modified to return an exit code similar to how org.apache.hadoop.mapred.JobShell did it.
