Todd Lipcon resolved HDFS-2579. ------------------------------- Resolution: Fixed Fix Version/s: HA branch (HDFS-1623) Hadoop Flags: Reviewed Committed to HA branch, thanks for the reviews. > Starting delegation token manager during safemode fails > ------------------------------------------------------- > > Key: HDFS-2579 > URL: https://issues.apache.org/jira/browse/HDFS-2579 > Project: Hadoop HDFS > Issue Type: Sub-task > Components: ha, name-node, security > Affects Versions: HA branch (HDFS-1623) > Reporter: Todd Lipcon > Assignee: Todd Lipcon > Fix For: HA branch (HDFS-1623) > > Attachments: hdfs-2579.txt, hdfs-2579.txt, hdfs-2579.txt > > > I noticed this on the HA branch, but it seems to actually affect non-HA > branch 0.23 if security is enabled. When the NN starts up, if security is > enabled, we start the delegation token secret manager, which then tries to > call {{logUpdateMasterKey}}. This fails because the edit logs may not be > written while in safe-mode. > It seems to me that there's not any necessary reason that you have to make a > new master key at startup, since you've loaded the old key when you load the > FSImage. You'd only be lacking a DT master key on a fresh cluster, in which > case we could have it generate one at format time. -- This message is automatically generated by JIRA.
