Remove the 'shutdownHook' in SingleProcessHBaseCluster where we close the FileSystem instance of a region server.
Set DistributedFileSystem cache to false when creating MiniMRCluster so when shutting down MiniMRCluster it will not close the shared FileSystem instance.
Also re-enable TestExportSnapshot.

(cherry picked from commit d11ee6a)

The failed UTs should not be related, and also fail in nightly build for branch-2.

Let me merge and file other issue for fixing branch-2 builds.
