Subject [jira] [Commented] (HADOOP-9717) Add retry flag/retry attempt count to the RPC requests
Date Wed, 10 Jul 2013 09:03:49 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-9717?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13704336#comment-13704336
] 

Steve Loughran commented on HADOOP-9717:
----------------------------------------

a byte is fairly compact and would let you track some multi-retry problems if you are packet
sampling; client just needs to stop incrementing once it is at 0xff.

> 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.
