> This is a bug introduced by PIG-3342 - Allow conditions in case statement.
> If 1) there are an even number of when branches, and 2) there is the else
> branch, case statement with conditions fails with the following error:
> {code}
> Caused by: org.apache.pig.impl.logicalLayer.validators.TypeCheckerException:
> ERROR 1057:
> <line 2, column 14> LOGenerate expression plan can only have one output
> {code}
> This is because the logic of determining whether case statement has the else
> branch is incorrect. This doesn't happen when conditions are not used in case
> statement.
