Summary: Support AvailableSpaceBlockPlacementPolicy in
BlockPlacementPolicyRackFaultTolerant
Key: HDFS-15511
URL: https://issues.apache.org/jira/browse/HDFS-15511
Project: Hadoop HDFS
Issue Type: Improvement
Reporter: Amithsha
As per BlockPlacementPolicyRackFaultTolerant, one block per rack is placed but
due to this Heterogeneous datanodes are not supported in Hadoop3. So we need to
change the BlockPlacementPolicyRackFaultTolerant to place one block on a rack
with the AvailableSpaceBlockPlacementPolicy feature.
