Subject [jira] Commented: (HDFS-914) Refactor DFSOutputStream and DFSInputStream out of DFSClient
Date Fri, 05 Feb 2010 18:13:28 GMT

Todd Lipcon commented on HDFS-914:
----------------------------------

The failed tests were unrelated - those same errors have shown up on a lot of test-builds
recently. I ran TestDatanodeBlockScanner locally on a patched tree and it passed. Sorry that
I didn't comment here.

> I'd like to propose refactoring DFSClient to extract DFSOutputStream and DFSInputStream
into a new org.apache.hadoop.hdfs.client package. DFSClient has become unmanageably large,
containing 8 inner classes.and approaching 4kloc. Factoring out the non-static inner classes
will also make them easier to test in isolation.
