Subject [jira] [Created] (HDFS-8338) SimulatedFSDataset support multiple storages/volumes
Date Thu, 07 May 2015 07:15:01 GMT
Walter Su created HDFS-8338:

             Summary: SimulatedFSDataset support multiple storages/volumes
                 Key: HDFS-8338
                 URL: https://issues.apache.org/jira/browse/HDFS-8338
             Project: Hadoop HDFS
          Issue Type: Improvement
            Reporter: Walter Su
            Assignee: Walter Su
            Priority: Minor

Some tests(like Mover/Balancer) move block among storages.
The tests use FsDatasetImpl because SimulatedFSDataset doesn't support multiple storages.
The tests can be faster if they utilize SimulatedFSDataset, only if SimulatedFSDataset support
multiple storages.
