> While Ozone client writes are going on, a container on a datanode can gets 
> closed because of node failures, disk out of space etc. In situations as 
> such, client write will fail with CLOSED_CONTAINER_IO. In this case, ozone 
> client should try to get the committed block length for the pending open 
> blocks and update the OzoneManager. While trying to get the committed block 
> length, it may fail with BLOCK_NOT_COMMITTED exception because as a part of 
> transiton from CLOSING to CLOSED state for the container , it commits all 
> open blocks one by one. In such cases, client needs to retry to get the 
> committed block length for a fixed no of attempts and eventually throw the 
> exception to the application if its not able to successfully get and update 
> the length in the OzoneManager. This Jira aims to address this.
