Description

Discussed in details here
The leak occurs while using Hadoop FileContext API:

• FileContext API internally uses AbstractFileSystem API which is implemented by org.apache.hadoop.fs.ozone.RootedOzFs when using ofs filesystem
• org.apache.hadoop.fs.ozone.RootedOzFs internally creates new RootedOzoneFileSystem()
• this RootedOzoneFileSystem is never closed and it may cause the leak
