> In case of ongoing writes by Ozone client to a container, the container might get closed
on the Datanodes because of node loss, out of space issues etc. In such cases, the operation
will fail with CLOSED_CONTAINER_IO exception. In cases as such, ozone client should try to
get the committed length of the block from the Datanodes, and update the KSM. This Jira aims 
to address this issue.
