Subject [jira] [Resolved] (HBASE-6314) Fast fail behavior for unauthenticated user
Date Thu, 05 Jul 2012 17:30:35 GMT

     [ https://issues.apache.org/jira/browse/HBASE-6314?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Andrew Purtell resolved HBASE-6314.

       Resolution: Fixed
    Fix Version/s: 0.94.1
     Hadoop Flags: Reviewed

Committed to trunk, 0.94, and 0.92 branches. Ran a few local tests on each branch to insure
the build is not broken. (We don't have test framework coverage for active Kerberos.)

> In case of unauthenticated users in secure hbase, hbase shell does a connection retry
at two levels:
> a) HConnection: It retries hbase.client.retries.number times in the getMaster()
> b) HBaseAdmin: it again retries hbase.client.retries.number times in its ctr
> So, hbase shell retries square number of times of the configured setting. We can make
it failfast (no retries) in case the user is not authenticated (no valid kerberos credentials).
