["Andrew Purtell (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HBASE-6877?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13594453#comment-13594453 ] 

Andrew Purtell commented on HBASE-6877:
---------------------------------------

[~anoop.hbase] you said on dev list you are seeing this? Does applying the patch fix it for you? Presumably [~zjushch] you've fixed this locally already?

We should commit this if people are hitting it.

> When we execute the coprocessor, we will called HTable#getStartKeysInRange first and get the Keys to exec coprocessor,
> if then some regions are split before execCoprocessor RPC, the Keys are something wrong now, and the result we get is not integrated, 
> for example:
> parent region is split into daughter region A and daughter region B,
> we executed coprocessor on the parent region, but the result data is only daughter region A or daughter region B
