-----------------------------------

             Summary: Coprocessor exec result is incorrect when region is in 
splitting 
                 Key: HBASE-6877
                 URL: https://issues.apache.org/jira/browse/HBASE-6877
             Project: HBase
          Issue Type: Bug
          Components: Coprocessors
    Affects Versions: 0.94.1
            Reporter: chunhui shen
            Assignee: chunhui shen
            Priority: Critical


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
