Subject [jira] [Commented] (HBASE-5682) Allow HConnectionImplementation to recover from ZK connection loss (for 0.94 only)
Date Sun, 01 Apr 2012 03:28:45 GMT

    [ https://issues.apache.org/jira/browse/HBASE-5682?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13243637#comment-13243637

Lars Hofhansl commented on HBASE-5682:
--------------------------------------

I am not envisioning any API changes, just that the HConnection would no longer be ripped
from under any HTables where there is a ZK connection loss.

I ran all tests again, and TestReplication and TestZookeeper have some failures that are related.
Looking.

> Just realized that without this HBASE-4805 is broken.
> I.e. there's no point keeping a persistent HConnection around if it can be rendered permanently
unusable if the ZK connection is lost temporarily.
> Note that this is fixed in 0.96 with HBASE-5399 (but that seems to big to backport)
