Description

FileContextMainOperationsBaseTest should randomize the name of the root directory it creates. It currently hardcodes LOCAL_FS_ROOT_URI to /tmp/test.

This causes the job to fail if it clashes with another jobs that also uses that path. Eg

org.apache.hadoop.fs.FileAlreadyExistsException: Parent path is not a directory: file:/tmp/test
