Jeff Zhang commented on TEZ-1358:
---------------------------------
Verify the 2 cases ( bad environment settings, localization failures ), which
cause container launch failed. The error messages looks clear to me, no need to
fix it. [~hitesh], please help confirm it.
The following are the error messages:
*bad environment settings*
