Subject [jira] Commented: (HADOOP-6656) Security framework needs to renew Kerberos tickets while the process is running
Date Tue, 28 Sep 2010 02:57:34 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-6656?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12915595#action_12915595
] 

Devaraj Das commented on HADOOP-6656:
-------------------------------------

Well, we started out by trying to make the Refreshable interface work (and Owen had posted
a patch on that on this jira). But we couldn't get it working reliably, and hence switched
to the kinit based renewal. That seems to be working well so far in our production.

> While a client process is running, there should be a thread that periodically renews
the Kerberos credentials to ensure they don't expire.
