Hanisha Koneru updated HDDS-267:
--------------------------------
Description:
During container update and close, the .container file on disk is modified. We
should make sure that the in-memory state and the on-disk state for a container
are consistent.
A write lock is obtained before updating the container data during close or
update operations.
During update operation, if the on-disk update of .container file fails, then
the container metadata is in-memory is also reset to the old value.
During close operation, if the on-disk update of .container file fails, then
the in-memory containerState is set to CLOSING so that no new operations are
permitted.
