@erikdw I am not sure I follow when you wrote:

group in git revert or git cherry-pick.
In the first git log example I gave in my [earlier
comment](https://github.com/apache/storm/pull/2550#issuecomment-363955298), how
can one find out from git log (i.e. commit history) that SHAs ad7360507,
0ddc41154, 5d9ad1eaa, f758123b5, e42ae4de8, 533ef7ad2 all belong to JIRA
STORM-2937.
Perhaps you mean it is possible to do it from GitHub?
