Lokesh Jain updated HDDS-2299:
------------------------------
Description: In SCM, BlockManager#allocateBlock does not allocate a block
in the excluded pipelines or datanodes if requested by the client. But there
can be cases where excluded pipelines and datanodes are the only ones left. In
such a case SCM should allocate a block in such pipelines and return to the
client. The client can choose to use or discard the block. (was: In SCM,
