---------------------------------
Summary: BlockManager should allocate a block in excluded
pipelines if none other left
Key: HDDS-2299
URL: https://issues.apache.org/jira/browse/HDDS-2299
Project: Hadoop Distributed Data Store
Issue Type: Bug
Components: SCM
Reporter: Lokesh Jain
Assignee: Lokesh Jain
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 are the only pipelines 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.
