Subject [jira] [Commented] (HBASE-18021) Add more info in timed out RetriesExhaustedException for read replica client get processing,
Date Fri, 12 May 2017 00:08:04 GMT

    [ https://issues.apache.org/jira/browse/HBASE-18021?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16007405#comment-16007405

huaxiang sun commented on HBASE-18021:
--------------------------------------

[~enis], can you help to review the patch? The info added  is helpful to debug timeout issues
with read replica, we just applied it to one case we are working on and it helped. [~zyork]
helped to review the patch but I guess it needs a committer's review to commit. Sorry if I
am wrong [~zyork], thanks!

> Right now, when the client does not receive results from replica servers within configured
timeout period, the client does not print out info which helps to understand/identify the
cause. Please see
> https://github.com/apache/hbase/blob/master/hbase-client/src/main/java/org/apache/hadoop/hbase/client/RpcRetryingCallerWithReadReplicas.java#L212
> More info needs to be filled in the exception so it helps to pinpoint the root cause
quickly.
