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.
