Subject [jira] [Commented] (HADOOP-9912) globStatus of a symlink to a directory does not report symlink as a directory
Date Thu, 05 Sep 2013 01:36:52 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-9912?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13758653#comment-13758653
] 

Colin Patrick McCabe commented on HADOOP-9912:
----------------------------------------------

Agree with Binglin that we don't want to follow symlinks in listStatus.  In general, I'd like
to avoid changing HDFS or LocalFileSystem semantics at all.  I also would like to avoid having
LocalFileSystem semantics diverge from HDFS.

Does a webex on Friday (Sep 6) sound good?  If so, I will set up a dial-in number and post
it here.

My suggestion for Pig would be to simply follow symlinks in Pig whenever you find them.  That
is, if {{FileStatus#isSymlink}} is true, call {{FileSystem#getFileStatus}} on the path to
get the target.  That should work on both the new and old Hadoop, and require no other changes.
 (Unless there's something I'm missing here, which is possible...)

> globStatus for a path that is a symlink to a directory used to report the resulting FileStatus
as a directory but recently this has changed.
