Andrew Purtell commented on HBASE-10581: ---------------------------------------- Yes an upgrade script should just delete these znodes. They are only a cache of persisted data. This can be documented. Related question is why can't all ZK znodes be cleared before upgrade? Probable answer: Replication. But that is the subject of another JIRA. :-) > ACL znode are left without PBed during upgrading hbase0.94* to hbase0.96+ > ------------------------------------------------------------------------- > > Key: HBASE-10581 > URL: https://issues.apache.org/jira/browse/HBASE-10581 > Project: HBase > Issue Type: Bug > Affects Versions: 0.98.0, 0.96.0, 0.96.1 > Reporter: Jeffrey Zhong > Assignee: Jeffrey Zhong > > ACL znodes are left in the upgrade process when upgrading 0.94 to 0.96+ > Those 0.94 znodes will choke HMaster because their data aren't PBed. -- This message was sent by Atlassian JIRA (v6.1.5#6160)
