Kumar Ravi commented on HBASE-6945: ----------------------------------- stack and Ted, Thanks for your comments and feedback. 1. The version I found this issue impacting us was in Hbase-0.94.1. I just started looking at the trunk. Looks like I need to create a patch for the subclasses of ResourceChecker.ResourceAnalyzer(). I'll get a patch for trunk shortly after I understand this implementation, build and test it out. I have verified this patch applies and tests without any issues on 0.94.2RC3. If there is another version I need to try this on, please let me know. 2. stack, Re. your question about OSMXBean, I have opened another JIRA - https://issues.apache.org/jira/browse/HBASE-6965. I viewed the OSMXBean class as a related but separate issue since it could be used elsewhere. 3. I have a questions being new to this process: -How can I get this patch submitted for review/approval and eventually checked into both the Hbase-0.94 and trunk trees? In addition to the patch I attached above do I need to checkin my changes using svn? Although I am confident this patch should apply smoothly to HBase-0.94, I want to make sure I am not breaking the process.
