java.lang.RuntimeException: java.lang.ClassNotFoundException: org.apache.hadoop.hbase.ipc.WritableRpcEngine not found

Hi,

I have embedded the hbase-0.94.8.jar and other required jars in my OSGi
bundle.
The hbase-0.94.8 jar does have the following class -
org.apache.hadoop.hbase.ipc.WritableRpcEngine. 

I am still getting the following exception -

java.lang.RuntimeException: java.lang.ClassNotFoundException:
org.apache.hadoop.hbase.ipc.WritableRpcEngine not found from bundle
[java_cartridge]
	at org.apache.hadoop.conf.Configuration.getClass(Configuration.java:1004)
	at org.apache.hadoop.hbase.ipc.HBaseRPC.getProtocolEngine(HBaseRPC.java:99)

	at org.apache.hadoop.hbase.client.HTable.<init>(HTable.java:132)
	at
com.oracle.cep.hbase.impl.HBaseConnection.<init>(HBaseConnection.java:103)


What could be the cause and solution for this?

Thanks in advance for any help.

Rgds,
Yogesh

This problem was due to older version of the hadoop core jar.
It is now solved.
