help-bash would be a better choice than bug-bash.

Since you did not show the code that is failing, there's not much we
can do.

If you believe that your "hadoop" command should have returned 1,
but bash believes that it returned 0, then perhaps the bug is in this
"hadoop" command.

Of course, since we have no idea what your bash code actually says,
we can't conclude much of *anything* at this point.
