Subject [jira] [Created] (HDFS-2195) Refactor StorageDirectory to not be an non-static inner class
Date Mon, 25 Jul 2011 22:02:09 GMT
Refactor StorageDirectory to not be an non-static inner class
-------------------------------------------------------------

                 Key: HDFS-2195
                 URL: https://issues.apache.org/jira/browse/HDFS-2195
             Project: Hadoop HDFS
          Issue Type: Improvement
          Components: data-node, name-node
    Affects Versions: 0.23.0
            Reporter: Todd Lipcon
            Assignee: Todd Lipcon


While working on HDFS-1073 I continually found it inconvenient that StorageDirectory is a
non-static inner class of Storage. This makes testing more complicated, and also has unintuitive
results, like {{sd.read()}} having side effects on a Storage object.

I'd like to try to make it a static inner class so that these side effects are clearer and
it's easier to use in isolation.
