Todd Lipcon updated HDFS-2579: ------------------------------ Issue Type: Sub-task (was: Bug) Parent: HDFS-1623 > 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: name-node, security > Affects Versions: 0.23.0 > Reporter: Todd Lipcon > Assignee: Todd Lipcon > > 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.
