Subject [jira] Commented: (HADOOP-2566) need FileSystem#globStatus method
Date Wed, 16 Jan 2008 00:41:34 GMT

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

Stat2Paths is public because I expect that users need to use it after we remove listPath etc.
in release 0.17. OK, I will put it in FileUtil.

I am thinking to keep globPath for now. After we make changes in FSShell, then we decide if
we can live without it.

> 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.
