Subject [jira] Commented: (HDFS-501) Use enum to define the constants in DataTransferProtocol
Date Mon, 27 Jul 2009 17:42:15 GMT

    [ https://issues.apache.org/jira/browse/HDFS-501?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12735677#action_12735677

Tsz Wo (Nicholas), SZE commented on HDFS-501:

Got no failure in unit tests this time.  (TestBackupNode is really unrelated to this.  The
patch does not fix it.)

It is better to replace them by enums.
