Currently RoundRobinVolumeChoosingPolicy use a shared index to choose volumes in HDFS with heterogeneous storages, this leads to non-RR choosing mode for certain type of storage.
Besides, it uses a shared lock for synchronization which limits the concurrency of volume choosing process. Volume choosing threads that operating on different storage types should be able to run concurrently.
