It is not me who did the HADOOP configuration, the HADOOP_CLASSPATH is set to:
HADOOP_CLASSPATH=$HBASE_HOME/hbase-0.20.3.jar:$HBASE_HOME/hbase-0.20.3-test.jar:$HBASE_HOME/lib/zookeeper-3.2.2.jar:$HBASE_HOME/conf Instead of using the build hbase jar, it uses the jar files from distribution, any problem with this? The working code uses the Tool+ToolRunner+JobConf classes from the mapred package, it correctly loaded the configuration.
