Subject [jira] [Commented] (HADOOP-9717) Add retry flag/retry attempt count to the RPC requests
Date Sat, 13 Jul 2013 14:15:49 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-9717?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13707743#comment-13707743
] 

Tsz Wo (Nicholas), SZE commented on HADOOP-9717:
------------------------------------------------

The retry number is also needed in the client side since client needs to find out the request
corresponding to the response received.  (We currently use a hashtable to store the calls
in the client side.)

> RetryCache lookup on server side implementation can be optimized if Rpc request indicates
if the request is being retried. This jira proposes adding an optional field to Rpc request
that indicates if request is being retried.
