[jira] [Commented] (PIG-5330) DUMP throws IOException but it
DESCRIBE's the schema
[ https://issues.apache.org/jira/browse/PIG-5330?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16350484#comment-16350484 ]
TamilArasu Perumal commented on PIG-5330:
-----------------------------------------
Pig doesn't like the implicit conversion. it has to be explicit
Ex.: memberId AS MemberId:long (memberId was an integer but doesn't convert that to long)
i had to modify the line to (long) memberId AS MemberId.
It is working now, I am closing with the above so it can be helpful for the other developers if they see this generic error.

> 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
> Priority: Major
>
> 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)
