Subject [jira] Commented: (HDFS-222) Support for concatenating of files into a single file
Date Tue, 27 Oct 2009 23:26:59 GMT

    [ https://issues.apache.org/jira/browse/HDFS-222?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12770697#action_12770697
] 

Hairong Kuang commented on HDFS-222:
------------------------------------

Hope that this is the last comment :-)
1. FSNamesystem.java: no need isDirectory() check on INodeFile.
2. FSDirectory.java: optimization: when removing src inode, no need to traverse src path to
get all inodes on the path again since src inode and its ancestor indoes are known.
