Subject [jira] [Commented] (HDFS-5898) Allow NFS gateway to login/relogin from its kerberos keytab
Date Tue, 04 Mar 2014 18:07:31 GMT

    [ https://issues.apache.org/jira/browse/HDFS-5898?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13919715#comment-13919715
] 

Daryn Sharp commented on HDFS-5898:
-----------------------------------

Quick glance, in the client cache, you don't want to re-initialize the ugi conf or force a
new login.  Maybe just use {{realUser.checkTGTAndReloginFromKeytab}} before creating the proxy
user.  However that's probably not even necessary because the RPC client will relogin from
keytab when the TGT goes bad.
