Re: about JDK versions
Dear Lisen,
HBase and Hadoop works well in JDK7u11. I know few that are in production.
http://sreevaddi.blogspot.com/2012/05/hadoop-200-alpha-standalone-and-jdk7u4.html

hadoop eco systems compiled in 6 running in 7.
I compiled in 7u4 and run in 7u4, too.  Will post a link, later.
Also, drill works well on my local 7u15.

Thanking you.
With Regards
Sree

Thanks Philip!

I have no concern about jdk 7 indeed. Just hopes HBase and Hadoop guys
could get this done sooner, for example,

https://issues.apache.org/jira/browse/HBASE-5261
