Hadoop Pig: java.lang.NoClassDefFoundError: org/apache/hadoop/hbase/filter/Filter

0 votes

This is my Pig-script:

register /usr/lib/zookeeper/zookeeper-3.4.3-cdh4.1.2.jar
register /usr/lib/hbase/hbase-0.92.1-cdh4.1.2-security.jar
register /usr/lib/hbase/lib/guava-11.0.2.jar

raw_data = LOAD 'input.csv' USING PigStorage( ',' ) AS (
listing_id: chararray,
fname: chararray,
lname: chararray );

STORE raw_data INTO 'hbase://sample_names' USING org.apache.pig.backend.hadoop.hbase.HBaseStorage ('info:fname info:lname');

Now, I run this command:

pig -x local hbase_sample.pig

I get following error message

This seems like a problem with the PATH. Please make sure you have set all the paths right. Especially the PIG_CLASSPATH

export PIG_CLASSPATH=”`hbase classpath`:$PIG_CLASSPATH”
