Subject [jira] [Updated] (HDFS-1991) HDFS-1073: Some refactoring of 2NN to easier share code with BN and CN
Date Wed, 25 May 2011 01:16:47 GMT

     [ https://issues.apache.org/jira/browse/HDFS-1991?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Todd Lipcon updated HDFS-1991:
------------------------------

    Attachment: hdfs-1991.txt

Fairly straightforward patch that moves the "guts" of the 2NN into static methods. In a later
patch, the CN/BN will be able to use these same methods, hopefully.

> Currently the Checkpointer class shares a lot of very similar code with the secondary
namenode.
> This JIRA is to do a little cleanup in SecondaryNameNode that will make it easier to
share code with the BackupNode and CheckpointNode.
