[jira] [Updated] (TEZ-2394) Issues when there is an error in VertexManager callbacks

     [ https://issues.apache.org/jira/browse/TEZ-2394?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Bikas Saha updated TEZ-2394:
----------------------------
    Attachment: TEZ-2394.1.patch

There is a subtle race condition that may cause this. It does not reveal a bug but it shows that the Precondition check was not correct. Since this is a rare race condition between threads, I have no way to test it. So instead I have added other Preconditions and error reporting to shed more light in case the fix in the patch is not correct. The fix in this patch is to remove the Preconditions since its not valid. Explanation in the comments in the code. [~hitesh] Please review.
