Nanda kumar commented on HDDS-1448:
-----------------------------------

Thanks [~avijayan] for the contribution and thanks to [~msingh] for reporting this. Committed
it to trunk.

[~jnp] / [~swagle], this is a temporary solution. This logic should be changed as part of
multi-raft support.

> While allocation pipelines, Ratis pipeline provider considers all the pipelines irrespective
of the state of the pipeline. This can lead to case where all the datanodes are up but the
pipelines are in closing state in SCM.
