Hi all,

when starting HBase on a single node have following exceptions in log files:

=====================================javax.management.NotCompliantMBeanException:

=====================================
Yes, I know about
https://issues.apache.org/jira/browse/HBASE-5718
and about
https://issues.apache.org/jira/browse/HBASE-5971

Also looked at:
http://stackoverflow.com/questions/10020702/jmx-exception-caused-by-java-lang-classnotfoundexception-lbyte

I didn't config JMX beans in hbase-site.xml (should I do this?). The only
config is ( hbase-site.xml):
=====================<configuration>
  <property>
    <name>hbase.rootdir</name>
    <value>file:///data/hbase</value>
  </property>
  <property>
    <name>hbase.zookeeper.property.dataDir</name>
    <value>/data/zookeeper</value>
  </property>
</configuration>
=====================
It seems that hbase developers do not consider this JMX issue  as a
noticeable problem. Am I right?

Best regards,
Ivan P. Ryndin,

HBASE-5718 seems to say it's reproducible only on openjdk.
HBase requires the jdk from Oracle (see
http://hbase.apache.org/book.html#basic.prerequisites).
Issues that occur on other jdk are not rejected, but usually receives a
lower priority. If someone provides a patch, it will be integrated.

Hi Nicolas,

thank you for the answer!
Yep, you are right, this is the problem with OpenJDK.
System is: Centos 64bit, java-1.6.0-openjdk-1.6.0.0.x86_64, HBase
0.94.3, java version "1.6.0_24"

Ok, I agree that the problem is not so critical.
Thank you again!
