FileSyste.globPaths does not validate the return list of Paths
--------------------------------------------------------------
Key: HADOOP-2151
URL: https://issues.apache.org/jira/browse/HADOOP-2151
Project: Hadoop
Issue Type: Bug
Components: dfs
Affects Versions: 0.15.0, 0.14.3
Reporter: lohit vijayarenu
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.
