-------------------------------------
The most problematic failure is the one in testNewNamenodeTakesOverWriter.
Exception details:
{code}testNewNamenodeTakesOverWriter(org.apache.hadoop.hdfs.qjournal.TestNNWithQJM)
Time elapsed: 2089 sec <<< ERROR!
java.io.IOException: The process cannot access the file because another process
has locked a portion of the file

This tests starts one namenode and then attempts to copy the image files. It
fails on Windows since the files are open without shared read permissions.
Fixing it would require changing the name node to use native File IO.
I propose fixing testMismatchedNNIsRejected and testWebPageHasQjmInfo and
skipping testNewNamenodeTakesOverWriter on Windows for now.
We can file a separate JIRA for the name node change which I expect to be a
more involved fix.
