huaxiang sun commented on HBASE-19848:

Hi [~Key Hutu], as Ted mentioned, you can use the submit-patch script to submit the patch.
Or use git diff to create a patch by 

"git diff --no-prefix". [~yuzhihong@gmail.com] and [~saint.ack@gmail.com], can you add [~Key
Hutu] to contributor list so he can assign the Jira to himself? Thanks.
