HBase Forum

NoClassDefFoundError: /org/apache/hadoop/hbase/HBaseConfiguration

    I am trying to run a map reduce program that will process and then insert the data into HBase. But then its giving me following error: NoClassDefFoundError: /org/apache/hadoop/hbase/HBaseConfiguration. So I added HBase jar in the CLASSPATH and tried to run but then it gave following Exceptions: NoClassDefFoundError: com/google/protobuf/Message. Any Suggestions?
    – Thanks

    Hi Sourabh,

    The protobuf-java.*.jar is not in the classpath. How are you running your mapred job?
    One way is to use HADOOP_CLASSPATH=`${HBASE_HOME}/bin/hbase classpath`, this will incorporate hbase classpath. Then you can run hadoop jar …. for your mapred job.
