[jira] Updated: (HADOOP-1397) Replace custom hbase locking with java.util.concurrent.locks.ReentrantLock

     [ https://issues.apache.org/jira/browse/HADOOP-1397?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

stack updated HADOOP-1397:
--------------------------

    Attachment: hadoop1397.patch

Here is a patch that replaces all instances of HLocking with instances of ReentrantReadWriteLock.

Hairong Kuang:  Any chance you'd try this patch on your machine first before I mark this issue with patch available'.  I would like to be sure that this patch does not introduce regression of HADOOP-1341 "TestHBaseCluster fails with IllegalMonitorStateException" (I've run unit tests on a couple of machines, both single and multiprocessor and it passes fine).  Thanks Hairong.

> HBase has a locking class that is effectively a clone of java.util.concurrent.locks.ReentrantLock.  This issue is about replacing HLocking with the java native implementation.
