Subject [jira] [Created] (HDFS-6340) DN can't finalize upgarde
Date Sun, 04 May 2014 16:27:14 GMT
Rahul Singhal created HDFS-6340:
-----------------------------------

             Summary: DN can't finalize upgarde
                 Key: HDFS-6340
                 URL: https://issues.apache.org/jira/browse/HDFS-6340
             Project: Hadoop HDFS
          Issue Type: Bug
          Components: datanode
    Affects Versions: 2.4.0
            Reporter: Rahul Singhal


I upgraded a (NN) HA cluster from 2.2.0 to 2.4.0. After I issued the '-finalizeUpgarde' command,
NN was able to finalize the upgrade but DN couldn't (I waited for the next block report).

I think I have found the problem to be due to HDFS-5153. I will attach a proposed fix.
