-------------------------------------

Ozone 1.3.0 had been released and we currently have more than 600 open issues 
targeted for 1.3.0. I am moving the target field to 1.4.0.

If there is anything needs to be discussed about the Target Version, Please 
reach out to me via Apache email or Slack.

> Currrent pipeline has 3 states,  ALLOCATED, OPEN and CLOSED. 
> When create pipeline command is sent out to datanodes from SCM, this pipeline 
> is marked as ALLOCATED in SCM.  Once SCM received all 3 datanodes 
> confirmation of pipelinee creation, SCM will change pipeline's state from 
> ALLOCATED to OPEN.  
> Close pipeline process is similar.  Add a new CLOSING state to pipeline. When 
> close pipeline command is sent out to datanodes, pipeline will be marked as 
> CLOSING.  When all 3 datanode confirmed,  change pipeline state from CLOSING 
> to CLOSED.
