> HADOOP-16582 have changed the way how mkdirs() work:
> *Before HADOOP-16582:*
> All calls to mkdirs(p) were fast-tracked to FileSystem.mkdirs which were then 
> re-routed to mkdirs(p, permission) method. For ProxyFileSytem the call would 
> look like
> {code:java}
> FileUtiles.mkdir(p)  ----->  FileSystem.mkdirs(p) ---> 
> ProxyFileSytem.mkdirs(p,permission)
> {code}
> An implementation of FileSystem have only needed implement mkdirs(p, 
> permission)
> *After HADOOP-16582:*
> Since FilterFileSystem overrides mkdirs(p) method the new call to 
> ProxyFileSystem would look like
> {code:java}
> FileUtiles.mkdir(p) ---> FilterFileSystem.mkdirs(p) -->
> {code}
> This will make all the qtests fails with the below exception 
> {code:java}
> Caused by: java.lang.IllegalArgumentException: Wrong FS: 
> pfile:/media/ebs1/workspace/hive-3.1-qtest/group/5/label/HiveQTest/hive-1.2.0/itests/qtest/target/warehouse/dest1,
>  expected: file:///
> {code}
> Note: We will hit this issue when we bump up hadoop version in hive.
> So as per the discussion in HADOOP-16963 ProxyFileSystem would need to 
> override the mkdirs(p) method inorder to solve the above problem. So now the 
> new flow would look like
> {code:java}
> FileUtiles.mkdir(p)  ---->   ProxyFileSytem.mkdirs(p) ---> 
> ProxyFileSytem.mkdirs(p, permission) --->
> {code}
