Jinglun created HDFS-15295:
------------------------------

             Summary: AvailableSpaceBlockPlacementPolicy should use chooseRandomWithStorageTypeTwoTrial() for better performance.
                 Key: HDFS-15295
                 URL: https://issues.apache.org/jira/browse/HDFS-15295
             Project: Hadoop HDFS
          Issue Type: Improvement

The chooseRandomWithStorageTypeTwoTrial is introduced in HDFS-11535 for better performance.  I think the AvailableSpaceBlockPlacementPolicy should use this too.
