Subject [jira] [Updated] (HBASE-14544) Allow HConnectionImpl to not refresh the dns on errors
Date Mon, 05 Oct 2015 17:04:27 GMT

     [ https://issues.apache.org/jira/browse/HBASE-14544?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Elliott Clark updated HBASE-14544:
----------------------------------
       Resolution: Fixed
    Fix Version/s:     (was: 1.2.0)
     Release Note: By setting hbase.resolve.hostnames.on.failure to false you can reduce the
number of dns name resolutions that a client will do. However if machines leave and come back
with different ip's the changes will not be noticed by the clients. So only set hbase.resolve.hostnames.on.failure
to false if your cluster dns is not changing while clients are connected.
           Status: Resolved  (was: Patch Available)

> Some clusters will have static ip addresses and forced dns lookup can cause extra instability.
Allow users to tun that feature off, if wanted.
