Hmm ... that is strange. I see that you are using Gentoo ... I'm not that familiar with Gentoo way of setting java-config etc, so hope someone else can suggest Gentoo specific troubleshooting of your java environment.
Some additional things you can try are: 1) Switch JDK back to IcedTea and see if shell works now - switch it back to Sun JDK and confirm it breaks. 2) Turn on verbose:class in your jvm args to see where the jruby classes are being loaded from. This is to confirm that you are not picking up stray jruby jars from some other location on your classpath. 3) Is this a straight hbase-0.20.6 unzipped from the tar.gz file? Or is this something you built from scratch? --Suraj On Sun, Dec 19, 2010 at 7:50 PM, 陈加俊 <[email protected]> wrote: > Hi Suraj > > Thank you ! > > hbase-env.sh is follow: > > # The java implementation to use.
