Cheolsoo Park created PIG-3342:
----------------------------------
Summary: Allow conditions in case statement
Key: PIG-3342
URL: https://issues.apache.org/jira/browse/PIG-3342
Project: Pig
Issue Type: Improvement
Components: parser
Reporter: Cheolsoo Park
Assignee: Cheolsoo Park
Fix For: 0.12
PIG-3268 added case statement support. But conditions are currently not allowed
in when branches. For example,
{code}
CASE
WHEN i % 5 == 0 THEN '5n'
WHEN i % 5 == 1 THEN '5n+1'
WHEN i % 5 == 2 THEN '5n+2'
WHEN i % 5 == 3 THEN '5n+3'
ELSE '5n+4'
END
{code}
This is invalid now. However, it will be useful if it's allowed.
