> 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}
