Todd Lipcon updated HDFS-1462:
------------------------------

    Attachment: hdfs-1462.txt

Ran tests on this, got the following failures which also exist on trunk (filed 
JIRAs for all of these, most of which were previously reported in the comments 
on HDFS-96):
    [junit] Test org.apache.hadoop.hdfs.TestFileStatus FAILED (HDFS-1470)
    [junit] Test org.apache.hadoop.hdfs.TestHDFSTrash FAILED (timeout) 
(HDFS-1471)
    [junit] Test org.apache.hadoop.fs.TestFcHdfsSymlink FAILED (HDFS-1466)
    [junit] Test org.apache.hadoop.fs.TestHDFSFileContextMainOperations FAILED 
(HDFS-1466)
    [junit] Test org.apache.hadoop.hdfs.TestPipelines FAILED (HDFS-1467)
    [junit] Test org.apache.hadoop.hdfs.server.datanode.TestBlockReport FAILED 
(HDFS-1468)
    [junit] Test org.apache.hadoop.hdfs.server.namenode.TestBlockTokenWithDFS 
FAILED  (HDFS-1469)

This failed on the previous patch:
    [junit] Test org.apache.hadoop.hdfs.server.namenode.TestBackupNode FAILED 
(timeout)
with a somewhat obvious NPE. This new version of the patch addresses the issue 
and the test now passes.

> Before the major work in HDFS-1073, I'd like to do this refactor to clean up 
> the monster FSEditLog class. We can separate all the functions that take of 
> loading edits into an FSN from the functions that take care of writing edits, 
> rolling, etc.
