    Description

      FileSystemRMStateStore writes directly to the destination file when storing state. However if the RM were to crash in the middle of the write, the recovery method could encounter a partially-written file and either outright crash during recovery or silently load incomplete state.

      To avoid this, the data should be written to a temporary file and renamed to the destination file afterwards.
