Exception using EB v3.0.7 on Hadoop 2.0.0-cdh4.2.0

[Zhu Wayne]

Could it be a compatibility issue?

Here is my pig script:
register /home/uid/elephant-bird-pig-3.0.7.jar;
register /home/uid/json_simple-1.1.jar;
raw = load 'c.json' using com.twitter.elephantbird.pig.load.JsonLoader() as (json:map[]);
dump raw;


ERROR 2997: Unable to recreate exception from backed error: Error: Found interface org.apache.hadoop.mapreduce.Counter, but class was expected

org.apache.pig.impl.logicalLayer.FrontendException: ERROR 1066: Unable to open iterator for alias raw. Backend error : Unable to recreate exception from backed error: Error: Found interface org.apache.hadoop.mapreduce.Counter, but class was expected
        at org.apache.pig.PigServer.openIterator(PigServer.java:826)

Yes, it is compatibility issue.

Thanks. Could you send me the link to download EB 4.0? I can't find it anywhere and had hard time building from  GIT master branch.

How are setting your dependencies? These packages are available from maven.

Raghu.

Thanks. I am not setting dependencies. I just need to download and use them in my PIG scripts;
