hbase-0.90.4 unable to execute java application to retrieve hbase table
Hello,
I have installed HBase-0.90.4 on my local machine and as shown in "quick
start " i installed/configured in standalone mode using my local file
system of fedora-15. I have not started hadoop daemon assuming that its not
needed as its completely standalone config. All the required libs that
comes with the package are there. I faced lot of difficulty in compiling
the simple code itself.I set CLASSPATH, in hbase-env.sh set HBASE_CLASSPATH
but now it doen'n run. I took a code from the net and has created the
required table in the hbase.
When I am trying to execute a very basic java code using Hbase-0.90.4
API. some how it compiled but on execution it throws exception:
java MyLittleHBaseClient
Exception in thread "main" java.lang.NoClassDefFoundError:
org/apache/commons/logging/LogFactory
at org.apache.hadoop.conf.Configuration.<clinit>(Configuration.java:139)
at MyLittleHBaseClient.main(MyLittleHBaseClient.java:21)
Caused by: java.lang.ClassNotFoundException:
org.apache.commons.logging.LogFactory
at java.net.URLClassLoader$1.run(URLClassLoader.java:217)
at java.security.AccessController.doPrivileged(Native Method)
at java.net.URLClassLoader.findClass(URLClassLoader.java:205)

at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:294)
at java.lang.ClassLoader.loadClass(ClassLoader.java:266)
... 2 more
Kindly see if any one has experienced the same issue at any point of time.
As for me its a long way ahead, hbase over HDFS and then hadoop
cluster.......
Thanks & Regards

I just checked and I also include the hadoop dependency and exclude several
packages from.
see http://activequant.org/svn/aq2o/trunk/pom.xml for a working pom.

Re: hbase-0.90.4 unable to execute java application to retrieve hbase table
Posted by Ulrich Staudinger <us...@activequant.com>.
With maven it becomes quite trivial to create an hbase app.
You would add the hbase dependency:
<dependency>
<groupId>org.apache.hbase</groupId>
<artifactId>hbase</artifactId>
<version>${hbase.version}</version>
</dependency>
and possibly the hbase repository
<repository>
<id>hbase</id>
<url>https://repository.apache.org/content/repositories/releases/</url>
</repository>
and you are ready to go.
well, if you read into it, you'll understand what i say.

Re: hbase-0.90.4 unable to execute java application to retrieve hbase table
Posted by Ulrich Staudinger <us...@activequant.com>.
That's more a java related question.
With maven it is pretty straightforward to get this up and running, without
altering the CLASSPATH or even having HBase installed on your machine.
Do you use maven?
