[jira] [Created] (HDFS-12008) Improve the available-space block placement policy

Kihwal Lee created HDFS-12008:
---------------------------------

             Summary: Improve the available-space block placement policy
                 Key: HDFS-12008
                 URL: https://issues.apache.org/jira/browse/HDFS-12008
             Project: Hadoop HDFS
          Issue Type: Bug
          Components: block placement
    Affects Versions: 2.8.1
            Reporter: Kihwal Lee


AvailableSpaceBlockPlacementPolicy currently picks two nodes unconditionally, then picks one node. It could avoid picking the second node when not necessary.
