My problem is similar to this unanswered question :
[https://stackoverflow.com/questions/42140344/elephantbird-dependency-jars][1]
i have registered all jars mandatory for elephantbird to function.
REGISTER '/MyJARS/elephant-bird-hadoop-compat-4.1
REGISTER '/MyJARS/json-simple-1.1.jar';
REGISTER '/MyJARS/elephant-bird-pig-4.1.jar';
REGISTER '/MyJARS/elephant-bird-core-4.10.jar';
REGISTER '/MyJARS/google-collections-1.0.jar';
following links tell me these info : 1 : Loading data from HDFS does not work with Elephantbird
2 : how to load twitter data from hdfs using pig?
My current versions :
Hadoop: Hadoop 2.6.0-cdh5.7.3
Pig: Apache Pig version 0.12.0-cdh5.7.3 (rexported)
I receive following error :
ERROR 1070: Could not resolve com.twitter.elephantbird.pig.load.JsonLoader using imports: [, java.lang., org.apache.pig.builtin., org.apache.pig.impl.builtin.]
Any help is appreciated , I tried almost all possible solutions across web.

REGISTER '/MyJARS/elephant-bird-hadoop-compat-4.1
REGISTER '/MyJARS/json-simple-1.1.jar';
REGISTER '/MyJARS/elephant-bird-pig-4.14.jar';
REGISTER '/MyJARS/elephant-bird-core-4.10.jar';
REGISTER '/MyJARS/google-collections-1.0.jar';
