Subject [jira] [Commented] (HBASE-16510) Reset RpcController before retry
Date Tue, 30 Aug 2016 05:09:21 GMT

    [ https://issues.apache.org/jira/browse/HBASE-16510?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15448059#comment-15448059
] 

Duo Zhang commented on HBASE-16510:
-----------------------------------

CancellableRegionServerCallable will call its parent, RegionServerCallable's call method,
we will reset the RpcController there.

And for RpcRetryingCallable, it is only used in HBaseAdmin for some meta operations, there
is no RpcController in the Callable implementation.

> Later we will use RpcController to pass exceptions to upper layer, so we need to clear
the exception info before retry.
