---------------------------------------------
Resolution: Duplicate
This is duplicate of HADOOP-2057
> Hadoop Streaming shoulf fail if user process exits with non-zero exit code
> --------------------------------------------------------------------------
>
> Key: HADOOP-3303
> URL: https://issues.apache.org/jira/browse/HADOOP-3303
> Project: Hadoop Core
> Issue Type: Bug
> Components: contrib/streaming
> Reporter: Zheng Shao
> Assignee: Zheng Shao
>
> Hadoop streaming quietly ignores the user process exit code. This is
> extremely dangerous because the user won't notice the problem while the
> output data is likely to be corrupted or incomplete.
> User process may have read all input data into input buffer, and then finds a
> problem in the input data, and exit with an error code and hopes that hadoop
> streaming can capture that.
> The current hadoop streaming just put this exit code into a log file and
> ignores it.
