Subject [jira] [Updated] (HBASE-5682) Allow HConnectionImplementation to recover from ZK connection loss (for 0.94 only)
Date Sun, 01 Apr 2012 05:45:17 GMT

     [ https://issues.apache.org/jira/browse/HBASE-5682?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Lars Hofhansl updated HBASE-5682:
---------------------------------

    Priority: Critical  (was: Major)

Upped to "critical". Without this the HBase client is pretty much useless in an AppServer
setting where client can outlive the HBase cluster and ZK ensemble.
(Testing within the Salesforce AppServer is how I noticed the problem initially.)

> 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)
