Subject [jira] [Created] (PIG-5330) DUMP throws IOException but it DESCRIBE's the schema
Date Wed, 31 Jan 2018 19:18:00 GMT
TamilArasu Perumal created PIG-5330:
---------------------------------------

             Summary: DUMP throws IOException but it DESCRIBE's the schema
                 Key: PIG-5330
                 URL: https://issues.apache.org/jira/browse/PIG-5330
             Project: Pig
          Issue Type: Bug
         Environment: Hortonworks - hadoop platform. But code is running local using Junit
test method
            Reporter: TamilArasu Perumal


This started happening recently for some JOINs and ORDER BY clause. Not sure anything to do
with the java update. Currently running Java 8 (161). Here is the pig code and log 

memberIds: \{newMemberId: long,memberId: long}

memberTier: \{Name: chararray,MemberId: long,TierId: long,StartDateId: long,EndDateId: long}

DUMP memberTier; – works fine
DESCRIBE memberTier; – works fine 
DUMP memberIds; – works fine
DESCRIBE memberIds; – works fine
memberTierOne = JOIN memberTier BY (MemberId) LEFT OUTER, memberIds BY (memberId);
DUMP memberTierOne; – errors out (if commented, the next line works)
DESCRIBE memberTierOne; – (works fine, when DUMP is commented)
