Subject [jira] [Commented] (HBASE-7649) client retry timeout doesn't need to do x2 fallback when going to different server
Date Fri, 25 Jan 2013 07:11:13 GMT

    [ https://issues.apache.org/jira/browse/HBASE-7649?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13562484#comment-13562484
] 

nkeywal commented on HBASE-7649:
--------------------------------

bq. Probably it works better with time based failure, not retry based.
Agreed, time based failure are quite interesting (I was the JIRA you created).
Linked to this, one option would be to send back to the client the time when the region was
moved. Then the client can do stuff like 'if the region was moved more than 10 seconds ago,
I can go to the new server"

> See HBASE-7520. When we go to server A, get a bunch of failures, then finally learn the
region is on B it doesn't make sense to wait for 30 seconds before going to B.
