DFSClient names in master and RS should be unique -------------------------------------------------
Key: HBASE-2975 URL: https://issues.apache.org/jira/browse/HBASE-2975 Project: HBase Issue Type: Bug Components: master, regionserver Affects Versions: 0.90.0 Reporter: Todd Lipcon Assignee: Todd Lipcon Priority: Critical Attachments: hbase-2975.txt In the post-newmaster trunk, there's some code which gives the regionserver and masters fancy names based on hostname and port. This breaks log recovery, though, if the master starts recovering a log (ie has an append lease on a log file), then crashes and comes back on the same port. The NN doesn't see this as a new client, since the client name is the same, so it thinks it still holds a lease on the file. The new master, though, can't call append() because the NN thinks it's appending, so it loops forever. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
