[jira] [Created] (HDFS-4894) Multiple Replica Placement Policies support in one HDFS cluster

Junping Du created HDFS-4894:
--------------------------------

             Summary: Multiple Replica Placement Policies support in one HDFS cluster
                 Key: HDFS-4894
                 URL: https://issues.apache.org/jira/browse/HDFS-4894
             Project: Hadoop HDFS
          Issue Type: Bug
            Reporter: Junping Du


We should allow multiple BPPs co-existing on the same HDFS cluster for different purpose of data and different types of application, i.e. we should allow some old, infrequently accessed data/directory to under RAID policy so that can save space.
