Subject [jira] [Created] (HDFS-3970) BlockPoolSliceStorage#doRollback(..) should use BlockPoolSliceStorage instead of DataStorage to read prev version file.
Date Tue, 25 Sep 2012 13:33:07 GMT
Vinay created HDFS-3970:
---------------------------

             Summary: BlockPoolSliceStorage#doRollback(..) should use BlockPoolSliceStorage
instead of DataStorage to read prev version file.
                 Key: HDFS-3970
                 URL: https://issues.apache.org/jira/browse/HDFS-3970
             Project: Hadoop HDFS
          Issue Type: Bug
          Components: data-node
    Affects Versions: 3.0.0, 2.0.2-alpha
            Reporter: Vinay
            Assignee: Vinay


{code}    // read attributes out of the VERSION file of previous directory
    DataStorage prevInfo = new DataStorage();
    prevInfo.readPreviousVersionProperties(bpSd);{code}

In the above code snippet BlockPoolSliceStorage instance should be used. other wise rollback
results in 'storageType' property missing which will not be there in initial VERSION file.
