Kihwal Lee updated HDFS-4780: ----------------------------- Fix Version/s: 2.0.5-beta 3.0.0 Hadoop Flags: Reviewed I've committed this to trunk and branch-2. > Use the correct relogin method for services > ------------------------------------------- > > Key: HDFS-4780 > URL: https://issues.apache.org/jira/browse/HDFS-4780 > Project: Hadoop HDFS > Issue Type: Bug > Components: namenode > Affects Versions: 3.0.0, 2.0.5-beta, 0.23.8 > Reporter: Kihwal Lee > Assignee: Robert Parker > Priority: Minor > Fix For: 3.0.0, 2.0.5-beta > > Attachments: HDFS-4780-branch0.23v1.patch, HDFS-4780v1.patch > > > A number of components call reloginFromKeytab() before making requests. For > StandbyCheckpointer and SecondaryNameNode, where this can be called > frequently, it generates many WARN messages like this: > WARN security.UserGroupInformation: Not attempting to re-login since the last > re-login was attempted less than 600 seconds before. > Other than these messages, it doesn't do anything wrong. But it will be nice > if it is changed to call checkTGTAndReloginFromKeytab() to avoid the > potentially misleading WARN messages. -- This message is automatically generated by JIRA.
