Olga Natkovich commented on PIG-1550: ------------------------------------- I will review the patch > better error handling in casting relations to scalars > ----------------------------------------------------- > > Key: PIG-1550 > URL: https://issues.apache.org/jira/browse/PIG-1550 > Project: Pig > Issue Type: Bug > Reporter: Olga Natkovich > Assignee: Thejas M Nair > Fix For: 0.8.0 > > Attachments: PIG-1550.1.patch > > > I ran the following script: > Input data: > joe 100 > sam 20 > bob 134 > Script: > A = load 'user_clicks' as (user: chararray, clicks: int); > B = group A by user; > C = foreach A generate group, SUM(A.clicks); > D = foreach A generate clicks/(double)C.$1; > dump C; > Since C contains more than 1 tuple, I expected to get an error which I did. > However, the error was not very clear. When the job failed, I did see a valid > error (however it lacked the error code): 210630 [main] ERROR > org.apache.pig.tools.pigstats.PigStats - ERROR 0: Scalar has more than one > row in the output > However at the end of processing, I saw a misleading error: > 210709 [main] ERROR org.apache.pig.tools.grunt.Grunt - ERROR 2088: Unable to > get results for: > hdfs://wilbur20.labs.corp.sp1.yahoo.com:9020/tmp/temp818551960/tmp1063730945:org.apache.pig.impl.io.InterStorage > 10/08/19 17:16:22 ERROR grunt.Grunt: ERROR 2088: Unable to get results for: > hdfs://wilbur20.labs.corp.sp1.yahoo.com:9020/tmp/temp818551960/tmp1063730945:org.apache.pig.impl.io.InterStorage -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
