Code discovering UDFs in the script has a bug in a order by case
----------------------------------------------------------------

                 Key: PIG-1534
                 URL: https://issues.apache.org/jira/browse/PIG-1534
             Project: Pig
          Issue Type: Bug
    Affects Versions: 0.7.0
            Reporter: Pradeep Kamath
             Fix For: 0.8.0


Consider the following commandline:
{noformat}
java -cp /tmp/svncheckout/pig.jar:udf.jar:clusterdir org.apache.pig.Main -e "a = load 'studenttab'
using udf.MyPigStorage(); b = order a by $0; dump b;"
{noformat}

Notice there is no "register udf.jar", instead udf.jar (which contains udf.MyPigStorage) is
in the classpath. Pig handles this case by shipping udf.jar to the backend. However the above
script with order by triggers the bug with the following error message:
 ERROR 2997: Unable to recreate exception from backed error: java.lang.RuntimeException: could
not instantiate 'org.apache.pig.impl.builtin.RandomSampleLoader' with arguments '[udf.MyPigStorage,
100]'
