Copy the hbase-*.jar inside tomcat's lib directory and try a re-run.

The exception clearly says that class org.apache.hadoop.hbase.filter.Filter is not found in the classpath. Please add hbase-X.X.X.jar to the class path of the application in tomcat. Please ensure that you use the correct version of hbase jar file.
