Subject [jira] [Commented] (HBASE-10357) Failover RPC's for scans
Date Wed, 14 May 2014 23:12:25 GMT

    [ https://issues.apache.org/jira/browse/HBASE-10357?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13998161#comment-13998161
] 

Enis Soztutar commented on HBASE-10357:
---------------------------------------

bq. let's leave it as is for now and if this becomes a problem, we can think of ways to address
it
Agreed that it is rare and not trivial to order this properly. 
bq. I wanted to make the ClientScanner totally unaware of the replica logic as well but at
the same time didn't want to make the ScannerCallableWithReplicas more complex than needed
I see. It seems that the model for openScanner + next from ClientScanner to ScannerCallable
is a little more complex in the usual case as well from what I thought. It should be ok for
now. 

+1 for the patch.
