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.
