Raghu Angadi commented on HADOOP-2566:
--------------------------------------
Assuming globPaths() goes away.. Should a user of globStatus() be able to
distinguish between a non-existent path and a glob that does not match any
files? If yes, how? Many hadoop shell commands treat these two differently (I
think that is consistent with normal shell behavior).
> need FileSystem#globStatus method

> Key: HADOOP-2566
> URL: https://issues.apache.org/jira/browse/HADOOP-2566
> Project: Hadoop
> Issue Type: Improvement
> Components: fs
> Reporter: Doug Cutting
> Assignee: Hairong Kuang
> Fix For: 0.16.0
>
>
> 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.
