Pradeep Kamath commented on PIG-1534: ------------------------------------- Thanks for the review Daniel, patch committed to trunk. > 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 > Assignee: Pradeep Kamath > Fix For: 0.8.0 > > Attachments: PIG-1534.patch > > > 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]' -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
