Re: Execution Error, return code 2 from org.apache.hadoop.hive.ql.exec.MapRedTask MapReduce Jobs Launched:
Hello Yogesh,

        Are any proxy settings involved??Error code 407 indicates that
the client must first authenticate itself with the proxy in order to
proceed further. Just make sure everything is in place.

Regards,
    Mohammad Tariq
