Reading hive table using Pig script


I am trying to read hive table using PIG script but when I run a pig code to read a table in hive its giving me following error
2014-02-12 15:48:36,143 [main] WARN  org.apache.hadoop.hive.conf.HiveConf - hive-site.xml not found on CLASSPATH
2014-02-12 15:49:10,781 [main] ERROR org.apache.pig.tools.grunt.Grunt - ERROR 2997: Unable to recreate exception from backed error: Error: Found class org.apache.hadoop.mapreduce.TaskAttemptContext, but interface was expected

Hadoop version

Hive version

Pig version

Pig code
a = LOAD '/user/hive/warehouse/test' USING org.apache.pig.piggybank.storage.HiveColumnarLoader('name string');

Is it due to some version mismatch ?
