> Running "hadoop.cmd jar" does not always propagate the exit code to the
> caller. In interactive use, it works fine. However, in some usages (notably
> Hive), it gets called through {{Shell#getRunScriptCommand}}, which needs to
> do an intermediate "cmd /c" to execute the script. In that case, the last
> exit code is getting dropped, so Hive can't detect job failures.
