Subject [jira] [Commented] (HDFS-2030) Fix the usability of namenode upgrade command
Date Thu, 09 Jun 2011 21:05:59 GMT

    [ https://issues.apache.org/jira/browse/HDFS-2030?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13046800#comment-13046800

Bharath Mundlapudi commented on HDFS-2030:

Thanks for the review, Suresh.
My comments inline.
1.1 Missing banner - done.
1.2 This method is package protected, this unit test just test this function instead of using
time consuming MiniDFSCluster.
1.3 Removed the null and empty checks.
1.4 BoolpoolID is autogenerated. Now i have modified the tests to not mock this. 
1.5 Added assertEquals where necessary
1.6 Made multiple tests

2.1 Since the setBlockPoolID() and setClusterID() are in NNStorage, i moved this function
to this class now solves this problem.
2.2 renamed the function
2.3 comments moved outside the function and moved the if condition inside the method.

Attaching the patch with these changes.
