[jira] [Created] (HDFS-9809) Abstract implementation-specific details from the datanode

Virajith Jalaparti created HDFS-9809:
----------------------------------------

             Summary: Abstract implementation-specific details from the datanode
                 Key: HDFS-9809
                 URL: https://issues.apache.org/jira/browse/HDFS-9809
             Project: Hadoop HDFS
          Issue Type: Task
            Reporter: Virajith Jalaparti


Multiple parts of the Datanode (FsVolumeSpi, ReplicaInfo, FSVolumeImpl etc.) implicitly assume that blocks are stored in java.io.File(s) and that volumes are divided into directories. We propose to abstract these details, which would help in supporting other storages.
