Hi,

I'm working on the Debian package for HBase. On Debian, the default JVM is 
OpenJDK, since it's free and the SUN JVM isn't much loved by the debian-java 
team.
Now when running HBase on OpenJDK 1.6.0_18 the master frontend shows the 
warning:
"Your current JVM version 1.6.0_18 is known to be unstable with HBase. Please 
see the HBase wiki  for details."

Has anybody already made experiences with running Hadoop/HBase on OpenJDK? 
Does the above warning also apply for this JVM?
For a broader addoption of Hadoop/HBase I'd recommend to do also testing on 
OpenJDK since I wouldn't be sure if the proprietary SUN JVM will remain much 
longer in Debian. (Don't know about Red Hat.)

Best regards,
