Hi Stack,
The NPE is this:

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

What about your hdfs's version?

Hi,
I have a cluster of 8 hdfs datanodes and 8 hbase regionservers. When I
shutdown one node(a pc with one datanode and one regionserver running), all
hbase regionservers shutdown after a while.
Other 7 hdfs datanodes is OK.
I think it's not reasionable. Hbase is a distribute system that
Hi Suraj
Thank you !
hbase-env.sh is follow:
# The java implementation to use. Java 1.6 required.
# export JAVA_HOME=/usr/java/jdk1.6.0/
export JAVA_HOME=/etc/java-config-2/current-system-vm
In addition ,
$ java-config -L
The following VMs are available for generation-2:

Can you check if your conf/hbase-env.sh is explicitly setting the JAVA_HOME
to the below 1.6.0_20 JRE? This overrides anything in the environment.
ClassFormatError suggests that either an older JRE is trying to read a
.class file compiled with a newer JRE. Or your library jar is somehow
corrupt.
Hi ryan
There is only one copy of hbase*.jar,and the md5sum is:
$ md5sum /app/cloud/hbase/hbase-0.20.6.jar
cb1af1f5df2e93ae58099a1608b22876 /app/cloud/hbase/hbase-0.20.6.jar
In addition, i wonder if is the question on which I used
zookeeper-3.3.2.jar.

If you are getting something like "java.lang.NoSuchMethodError"
usually this is due to multiple jars or misdeployed hbase.
check your hbase dir again, there should only be 1 copy of hbase*.jar,
if there are 2 and they are different (you can use md5sum to compare)
that could be the cause of the iss

Yep, I always leave that at the default, whatever that might be.

HBase doesn't hashcode anything. It does strict lexicographical ordering of
the row keys themselves. So yes, keys with similar prefixes may be in the same
partition / next to each other.
Rather than using a hashcode modulo some number, we use the META table to
determine which partition (regio

That was a great thread Todd... it almost got somewhere. Looks like
you were owed a response by the hotspot-gc crew.
Friso, I wonder if u23 is better? There are a bunch of G1 fixes in
it: http://www.oracle.com/technetwork/java/javase/2col/6u23bugfixes-191074.html

We happen to be looking at gigaspaces and hbase/hadoop. I read this in
the gigaspaces documentation...
