Hi Jean, This issue had been solved by following the suggestions of Cheolsoo
*1) ClassNotFoundError Even though you're "registering" jars in your script, they're not present in classpath. So you're seeing that ClassNotFound error. Can you try this? PIG_CLASSPATH=<hbase_home>/hbase-0.94.1.jar:<hbase_home>/ lib/zookeeper-3.4.3.jar:<hbase_home>/lib/protobuf-java-2.4.0a.jar ./bin/pig <your script> The best way to use HBaseStorage is to install the hbase client locally, so they're present in classpath automatically. Then, you don't have to add them to PIG_CLASSPATH. 2) pig-0.10.0.jar Can you also make sure that you use pig-0.10.0-withouthadoop.jar instead of pig-0.10.0.jar? Pig.jar embeds hbase-0.90, so you will run into **a compatibly issue if you run it against hbase-0.94*.
