Summary: Optimize AvailableSpaceBlockPlacementPolicy
Key: HDFS-17210
URL: https://issues.apache.org/jira/browse/HDFS-17210
Project: Hadoop HDFS
Issue Type: Improvement
Components: hdfs
Affects Versions: 3.3.6
Reporter: Fei Guo
for now ,we may have many nodes usage over 85%, some nodes'usage have been over
90%, if we choose three nodes as nodeA-97%,nodeB-98%,nodeC-99%, actually i
don't want nodeC(99%) be choosen, for nodeC usage is really high , even random
chance ,nodeC will reach 100% soon, so we can directly choose the less usage
node(nodeA) if all nodes's usage are over 95%(just a example)
