[jira] [Created] (HBASE-16172) Unify the retry logic in ScannerCallableWithReplicas and RpcRetryingCallerWithReadReplicas

Yu Li created HBASE-16172:
-----------------------------

             Summary: Unify the retry logic in ScannerCallableWithReplicas and RpcRetryingCallerWithReadReplicas
                 Key: HBASE-16172
                 URL: https://issues.apache.org/jira/browse/HBASE-16172
             Project: HBase
          Issue Type: Bug
            Reporter: Yu Li
            Assignee: Yu Li


The issue is pointed out by [~devaraj] in HBASE-16132 (Thanks D.D.), that in {{RpcRetryingCallerWithReadReplicas#call}} we will call {{ResultBoundedCompletionService#take}} instead of {{poll}} to dead-wait on the second one if the first replica timed out, while in {{ScannerCallableWithReplicas#call}} we still use {{ResultBoundedCompletionService#poll}} with some timeout for the 2nd replica.

This JIRA aims at discussing whether to unify the logic in these two kinds of caller with region replica and taking action if necessary.
