HADOOP-18242. ABFS Rename Failure when tracking metadata is in an incomplete state (#4517)
ABFS rename fails intermittently when the Storage-blob tracking
metadata is in an incomplete state. This surfaces as the error code
404 and an error message of "RenameDestinationParentPathNotFound"

To mitigate this issue, when a request fails with this response.
the ABFS client issues a HEAD call on the source file
and then retries the rename operation again

ABFS filesystem statistics track when this occurs with new counters
  rename_recovery
  metadata_incomplete_rename_failures
  rename_path_attempts

This is very rare occurrence and appears to be triggered under certain
heavy load conditions, just as with HADOOP-18163.
