[jira] [Created] (HBASE-6965) Generic MXBean Utility class to
support all JDK vendors
Kumar Ravi created HBASE-6965:
---------------------------------
Summary: Generic MXBean Utility class to support all JDK vendors
Key: HBASE-6965
URL: https://issues.apache.org/jira/browse/HBASE-6965
Project: HBase
Issue Type: Improvement
Components: build
Affects Versions: 0.94.1
Reporter: Kumar Ravi
Assignee: Kumar Ravi
Fix For: 0.94.3
This issue is related to JIRA https://issues.apache.org/jira/browse/HBASE-6945. This issue is opened to propose the use of a newly created generic org.apache.hadoop.hbase.util.OSMXBean class that can be used by other classes. JIRA HBASE-6945 contains a patch for the class org.apache.hadoop.hbase.ResourceChecker that uses OSMXBean. With the inclusion of this new class, HBase can be built and become functional with JDKs and JREs other than what is provided by Oracle.
This class uses reflection to determine the JVM vendor (Sun, IBM) and the platform (Linux or Windows), and contains other methods that return the OS properties - 1. Number of Open File descriptors; 2. Maximum number of File Descriptors.
This class compiles without any problems with IBM JDK 7, OpenJDK 6 as well as Oracle JDK 6. Junit tests (runDevTests category) completed without any failures or errors when tested on all the three JDKs.The builds and tests were attempted on branch hbase-0.94 Revision 1396305.

stack commented on HBASE-6965:
------------------------------
Here are some comments on this patch (Thanks for doing it).
In future, would suggest putting the two patches together... Having them separate makes it hard to review; I have to flip between two JIRAs to figure whether this thing of use or not?
The class is misnamed. This is not a management bean.
What JVMs and OS's did you test on out of interest? How many different vendor and OS strings did you test your patch against?
It seems a big hacky looking for 'IBM' in vendor string figuring if an IBM JVM or not. Are you sure it's always upper case. Any other property you could check to be sure it is the JVM you think. Does IBM only make a linux JDK?

stack commented on HBASE-6965:
------------------------------
[~kumarr] OSMXBean is a bad name for the class. It is not an MBean. I suggest that it be called JVM. We can make a new JIRA to rename it if you are in agreement (I can do it). Also, why not use exising http://hadoop.apache.org/docs/r0.20.0/api/org/apache/hadoop/util/Shell.ShellCommandExecutor.html instead of doing your own shell execution? instead of managing processes in your code added here? Thanks for list of classes and OS's tested on.

Kumar Ravi commented on HBASE-6965:
-----------------------------------
Opened new issue HBASE-7150 to address the comments listed above.
There is one recommendation that I have not been able to implement satisfactorily -- This is the one suggestion about using http://hadoop.apache.org/docs/r0.20.0/api/org/apache/hadoop/util/Shell.ShellCommandExecutor.html
When I attempted to use this hadoop API instead of the process management calls I had originally used, I was able to build and test successfully using the Sun and OpenJDK environments. With IBM JDK 7, although the build is successful, a number of tests returned errors with a NumberFormatException. At this point, this appears to be a bug with IBM JDK 7's Long class not being able to treat the string returned by ShellCommandExecutor properly, and hence the NumberFormatException. So I had to revert back to the process calls I had implemented.
When this issue is resolved, I can implement the ShellCommandExecutor call.

Do you think this should go into 0.94 as well ?

Kumar Ravi commented on HBASE-6965:
-----------------------------------
>What JVMs and OS's did you test on out of interest? How many different vendor and OS strings did you test your patch against?
This was tested on Sun (Oracle) JDK 6 (1.6.0_34), OpenJDK 6 and IBM Java 7. All tested on RHEL 6.3.
>It seems a big hacky looking for 'IBM' in vendor string figuring if an IBM JVM or not. Are you sure it's always upper case. Any other property >you could check to be sure it is the JVM you think. Does IBM only make a linux JDK?
We borrowed this idea from the code here in hadoop: http://svn.apache.org/repos/asf/hadoop/common/tags/release-1.0.3/src/core/org/apache/hadoop/security/UserGroupInformation.java. See methods getOSLoginModuleName() - Line 262 and getOsPrincipalClass() - Line 276.

--------------------------------
Hi Kumar,
The issue above is very unlikely to be caused by your patch. "precommit" is an environment where all tests are executed before being integrated. But some tests are, unfortunately, flaky. It's likely to be the cause here. The next step for your patch is to be reviewed and committed to trunk. Ted reviewed it already, so if he's ok he will commit it. If he does not look at it within two days I will have a look at it myself (or another committer will take the lead in between). Thanks for your contribution :-)

[jira] [Updated] (HBASE-6965) Generic MXBean Utility class to
support all JDK vendors
Posted by "Kumar Ravi (JIRA)" <ji...@apache.org>.

Kumar Ravi updated HBASE-6965:
------------------------------
Attachment: OSMXBean.java
Here's the source file for OSMXBean.java. This would reside in the src/main/java/org/apache/hadoop/hbase/util directory.

I think it's better to replace sun with Oracle.

Please add annotation for audience and stability for the above class.

Do you need to mention IBM in the above javadoc ?

-----------------------------------
Ted and nkeywal - Thanks for your comments and patience working with me on this Jira.
Ted, I'm working on addressing your concerns raised above. I do have one question:
Not sure what you mean by "Please add annotation for audience and stability for the above class."
I think by audience you mean when this class gets invoked? I am not clear about what you mean by stability.
If you could point me to some examples in the hbase code that would be great.

Kumar Ravi commented on HBASE-6965:
-----------------------------------
stack, ok - I agree this is not a management bean. I was trying to find an alternative to the Sun Management bean and borrowed the name from there. I can rename OSMXBean to JVMBean.
So just want to make sure I understand the process here - Do I open a new JIRA and rename the class name and submit a patch in that new JIRA? What happens to this JIRA then? What happens to the OSMXBean class and java file? How do I remove it from the tree?
I'll look at the ShellCommandExecutor in the new JVMBean class. What I am not clear about at this point if it provides any more functional value to what I already have there? But I'll look into it.
Please let me know if there is anything else I need to consider. I'll answer your questions in HBASE-6945 as well.

stack commented on HBASE-6965:
------------------------------
Yeah, you could open a new issue to rename (I think it should be JVM not JVMBean. Its not even a Bean not to mind a management Bean).
Regards the ShellCommandExecutor, it is not a case of whether it has more functionality than what you have added, its that we do not want repeated code in our code base which seems to be what is going on here. Correct me if I am wrong?
Thanks.

Kumar Ravi commented on HBASE-6965:
-----------------------------------
As suggested, I have combined the two patches into one. I ran above core tests with multiple JDKs before and after submitting the patch and have been unable to recreaet the problems in above builds. I understand that the problem reported in above pre-commit build is in the hbase-server area, whereas the patch above applies to the hbase-common module. Can someone suggest next steps on how to resolve this issue?

> This issue is related to JIRA https://issues.apache.org/jira/browse/HBASE-6945. This issue is opened to propose the use of a newly created generic org.apache.hadoop.hbase.util.OSMXBean class that can be used by other classes. JIRA HBASE-6945 contains a patch for the class org.apache.hadoop.hbase.ResourceChecker that uses OSMXBean. With the inclusion of this new class, HBase can be built and become functional with JDKs and JREs other than what is provided by Oracle.
> This class uses reflection to determine the JVM vendor (Sun, IBM) and the platform (Linux or Windows), and contains other methods that return the OS properties - 1. Number of Open File descriptors; 2. Maximum number of File Descriptors.
> This class compiles without any problems with IBM JDK 7, OpenJDK 6 as well as Oracle JDK 6. Junit tests (runDevTests category) completed without any failures or errors when tested on all the three JDKs.The builds and tests were attempted on branch hbase-0.94 Revision 1396305.
