hadoop 0.23+ ships with multiple jars instead of one hadoop-core-xxx.jar
in 0.20 or hadoop-1.
And the jar files are under share directory.
hadoop-0.23.0/share $ find . -name hadoop*.jar | grep -v source | grep
-v test
./hadoop/common/hadoop-common-0.23.0.jar
./hadoop/common/lib/hadoop-yarn-common-0.23.0.jar
./hadoop/common/lib/hadoop-yarn-api-0.23.0.jar
./hadoop/common/lib/hadoop-mapreduce-client-core-0.23.0.jar
./hadoop/common/lib/hadoop-mapreduce-client-app-0.23.0.jar
./hadoop/common/lib/hadoop-yarn-server-common-0.23.0.jar
./hadoop/common/lib/hadoop-mapreduce-client-common-0.23.0.jar
./hadoop/common/lib/hadoop-auth-0.23.0.jar
./hadoop/common/lib/hadoop-mapreduce-client-jobclient-0.23.0.jar
./hadoop/hdfs/hadoop-hdfs-0.23.0.jar
So far you need to make sure all the jars are placed under you hbase/lib
directory.

You need to replace the hadoop jar that is under hbase lib with that
of the cluster you are trying to communicate with.
Please read the reference guide. Its plain you have not.
