Hi everybody,

I'm having an issue when I start my HBase cluster. Is logged the following
error:

2012-10-23 14:59:53,894 INFO
org.apache.hadoop.hbase.regionserver.HRegionServer: Registered RegionServer
MXBean

The cluster not initializes anymore, and the HBase Web UI show that a region
is transitioning ad eternum. The java version on entire cluster is 1.6.0_24.

Anyone knows what is happening?

Exactly, What version of HBase are you using?

Wow! Thanks for the fast answer!

I'm using release 0.94.1, r1365210, with Hadoop 1.0.4 (HDFS).

Can you share you conf files?
Which is the size of your cluster?

Did you check that this PureJavaCrc32 class is under org.apache.hadoop.util?

It's a tiny test cluster, with five nodes. Below, the configuration files:

First, Hadoop config. files
______________________________________________
core-site.xml
______________________________________________
<configuration>
<property>
<name>hadoop.tmp.dir</name>
 <value>/opt/hadoop/tmp</value>
</property>
<property>
 <name>fs.default.name</name>
<value>hdfs://master.cluster.org:54310/</value>
 </property>
</configuration>
______________________________________________
hdfs-site.xml
______________________________________________
<configuration>
<property>
<name>dfs.replication</name>
 <value>3</value>
</property>
</configuration>
______________________________________________
masters file
______________________________________________
master.cluster.org
______________________________________________
slaves file
______________________________________________
node1.cluster.org
node2.cluster.org
node3.cluster.org
node4.cluster.org

We're not using Hadoop's MapReduce, only HDFS.

Now, configuration files for HBase.
______________________________________________
hbase-site.xml
______________________________________________

<configuration>
<property>
 <name>hbase.zookeeper.quorum</name>
<value>master.cluster.org</value>
 </property>
<property>
 <name>hbase.zookeeper.property.dataDir</name>
<value>/opt/hbase/zookeeper</value>
 </property>
<property>
<name>hbase.rootdir</name>
 <value>hdfs://master.cluster.org:54310/hbase</value>
</property>
 <property>
<name>hbase.cluster.distributed</name>
<value>true</value>
 </property>
</configuration>
______________________________________________
regionservers
______________________________________________
node1.cluster.org
node2.cluster.org
node3.cluster.org
node4.cluster.org.

Thanks in advance!
