stack updated HADOOP-1616:
--------------------------

    Attachment: hadoop-1616.patch

Found leaking file handles.  Was (on some machines) getting in the way of our running two
tests of a TestCase on MiniHBaseCluster.

HADOOP-1616 [hbase] Sporadic TestTable failures
Found a couple of leaking file handles that on some machines
prevented hdfs client shutting down its lease checker.  Was
stopping us moving on to next unit test in a Test Case.
M src/contrib/hbase/src/test/org/apache/hadoop/hbase/MiniHBaseCluster.java
    Add close of filesystem.  Will print out any leaking filehandles.
M src/contrib/hbase/src/test/org/apache/hadoop/hbase/TestScanner2.java
    Close region log.
M src/contrib/hbase/src/test/org/apache/hadoop/hbase/TestTableMapReduce.java
M src/contrib/hbase/src/test/org/apache/hadoop/hbase/AbstractMergeTestBase.java
    (createNewHRegion): Signature changed.
M src/contrib/hbase/src/test/org/apache/hadoop/hbase/HBaseTestCase.java
    (createNewHRegion): Refactored to use HRegion.createNewRegion.
M src/contrib/hbase/src/test/org/apache/hadoop/hbase/TestHLog.java
    Close and delete hlog.
M src/contrib/hbase/src/test/org/apache/hadoop/hbase/TestHRegion.java
    (tearDown): Added.  Close hlog.
M src/contrib/hbase/src/java/org/apache/hadoop/hbase/HLog.java
    Made logging more informative.  javadoc and formatting changes.

> Nightly failed in TestTable (though 'patch available' build passed and it passes all
tests locally).  The nightly failure has been reproduced on a machine here so looking into
it (DFSClient leaseChecker thread is staying up though minidfs has been shutdown -- it then
goes on to complain it can't connect to the destroyed 'remote' minidfs).
