(HConnectionManager.java:389)

hello,
is there a difference in initializing Javaclient for hbase 0.96.1.1 compared
to 0.94 ? 

Configuration hadoopConf = HBaseConfiguration.create();
hadoopConf.set("hbase.zookeeper.quorum", "192.168.111.212");
hadoopConf.set("hbase.zookeeper.property.clientPort", "2181");
HConnection connection = HConnectionManager.createConnection(hadoopConf);

leads to the following with 0.96.1.1 :

java.io.IOException: java.lang.reflect.InvocationTargetException
        at
org.apache.hadoop.hbase.client.HConnectionManager.createConnection(HConnectionManager.java:389)
        at
org.apache.hadoop.hbase.client.HConnectionManager.createConnection(HConnectionManager.java:366)
        at
org.apache.hadoop.hbase.client.HConnectionManager.getConnection(HConnectionManager.java:247)
        at
org.apache.hadoop.hbase.client.HBaseAdmin.<init>(HBaseAdmin.java:183)

regards and thx,

Yes of course. I have tried a few things:

1. The protobuf 2.5.0 you sujested was indeed needed and solved most of the
problem in the first place. Although I got other exceptions.

2. Then I saw I had lots of slf4j jars with different versions downloaded
from different modules. It might have solved the mystery navigate them to
use only one version (with maven exclusions).

3. There was another conflict between hadoop2.2.0 jersey and my own. I also
excluded the one shiped with hadoop. It solved other exceptions regarding
usage of new hadoop/hbase versions.

that was pretty much it and it might seem short but it took a lot of
frustration. The migration is successfull and my tests work fine. 

The last bothering issue is this winutil.exe that is required, which it
shouldn't, since my cluster installation is in an Ubuntu server but my
client in a win7. I have no installation in win7. The exception doesnt seem
to have influence on the functionality but it bothers a little bit so i told
my java code to find HBaseConnection a fake winuil.exe.

thanks again and regards,

Can you outline what jars caused the conflict so that other people can
solve similar problems more quickly ?

This is already in my hbase-site.xml file:

  <property>
    <name>hbase.rootdir</name>
    <value>hdfs://192.168.111.210:8020/hbase</value>
    <description>The directory shared by RegionServers.
    </description>
  </property>

The Code is simple:

Configuration hadoopConf = HBaseConfiguration.create();
hadoopConf.set("hbase.zookeeper.quorum", "192.168.111.212");
hadoopConf.set("hbase.zookeeper.property.clientPort", "2181");
// hadoopConf.set("hbase.rootdir", "hdfs://192.168.111.210:8020/hbase");
//!!?? this is not eeded    	
HConnection connection = HConnectionManager.createConnection(hadoopConf);

And like I said it always worked with hbase-0.94, but with 0.96.1.1-hadoop2
comes the exception.

I wonder what could be wrong here!!

You need to specify the following in your config (value portion is just a
sample):

<property>
<name>hbase.rootdir</name>
<value>
hdfs://y.net:8020/database
</value>
</property>

I really thank you for giving the tips. But the links I have studied before.
I have hbase-0.96.1.1-hadoop2 using hdfs of hadoop2.2.0. I have my code in
eclipse/win7 and the installation is ofcourse in an Ubuntu server. I
searched the web many times but couldn't find a solution. I would be
greatfull if I could get some answers here.

Can you check the version of protobuf jar in the classpath of your client ?

2.5.0 of protobuf is expected:

[INFO] |  +- com.google.protobuf:protobuf-java:jar:2.5.0:compile
