Subject [jira] Commented: (HADOOP-2151) FileSyste.globPaths does not validate the return list of Paths

Raghu Angadi commented on HADOOP-2151:
--------------------------------------

correction : Once there is glob, we can {{listPaths}} if a glob is specified for the component
otherwise check {{exists()}} for the component.. or something like that.. :) we don't need
to list all the 5k users for /user/foo/*/.

> FileSystem.globPaths does not validate the return list of Paths.
> Here is an example. 
> Consider a directory structure like
> /user/foo/DIR1/FILE1
> /user/foo/DIR2
> now if we pass an input path like "/user/foo/*/FILE1" to FileSystem.globPaths()
> It returns 2 entries as shown below
> /user/foo/DIR1/FILE1
> /user/foo/DIR2/FILE1
> Should globPaths validate this and return only valid Paths? This behavior was caught
in FileSystem.validateInput() where an IOException is thrown while processing such a directory
structure.
