Subject [jira] [Commented] (HDFS-4230) Listing all the current snapshottable directories
Date Thu, 03 Jan 2013 18:32:13 GMT

    [ https://issues.apache.org/jira/browse/HDFS-4230?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13543162#comment-13543162
] 

Suresh Srinivas commented on HDFS-4230:
---------------------------------------

bq. It may not be a good idea to have SnapshottableDirectoryStatus extending HdfsFileStatus
since most of the fields in HdfsFileStatus are not needed for SnapshottableDirectoryStatus.

I am fine making SnapshottableDirectoryStatus a subclass of HdfsFileStatus. That way we could
print lot more information about the directory it self, not just the snapshot related information.
HdfsFileStatus#path refers to the local name only. However SnapshottableDirectoryStatus requires
complete path.
