Subject [jira] Updated: (HDFS-627) Support replica update in datanode
Date Wed, 23 Sep 2009 00:47:17 GMT

     [ https://issues.apache.org/jira/browse/HDFS-627?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Tsz Wo (Nicholas), SZE updated HDFS-627:
----------------------------------------

    Attachment: h627_20090922.patch

h627_20090922.patch: only able to fix (1).

> 2. When finalizing a RUR, we need to make sure that the finalized data/meta files are
located in the "finalized" directory. Check FSDataset#finalizeBlock to see how a replica is
finalized.

I cannot see any codes in FSDataset#finalizeBlock checking "finalized" directory.  Could you
give me more hints?

3. Looks that we need to make sure that rbw#getBytesOnDiks() should be equal to rbw#getNumOfBytes()
when stopping a writer.. 

Then, it should be fixed in initReplicaRecovery(..), right?
