Subject [jira] Commented: (HADOOP-2566) need FileSystem#globStatus method
Date Fri, 11 Jan 2008 19:25:34 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-2566?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12558078#action_12558078
] 

Hairong Kuang commented on HADOOP-2566:
---------------------------------------

I do not see why we need globStatus. GlobPath is essentially pattern matching. If the provided
path does not contain any pattern, the given path is returned without talking to the namenode.

> To remove the cache of FileStatus in DFSPath (HADOOP-2565) without hurting performance,
we must use file enumeration APIs that return FileStatus[] rather than Path[].  Currently
we have FileSystem#globPaths(), but that method should be deprecated and replaced with a FileSystem#globStatus().
> We need to deprecate FileSystem#globPaths() in 0.16 in order to remove the cache in 0.17.
