[jira] [Updated] (SPARK-18048) If expression behaves differently if
true and false expression are interchanged in case of different data types.
[ https://issues.apache.org/jira/browse/SPARK-18048?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Priyanka Garg updated SPARK-18048:
----------------------------------
Description:
If expression behaves differently if true and false expression are interchanged in case of different data types.
For eg.
If(Literal.create(geo != null, BooleanType),
Literal.create(null, DateType),
Literal.create(null, TimestampType)) is throwing error while
If(Literal.create(geo != null, BooleanType),
Literal.create(null, TimestampType),
Literal.create(null, DateType )) works fine.
The reason for the same is that the If expression 's datatype only considers trueValue.dataType.
Also,
If(Literal.create(geo != null, BooleanType),
Literal.create(null, DateType),
Literal.create(null, TimestampType))
is breaking only in case of Generated mutable Projection and Unsafe projection. For all other types its working fine.
Either both should work or none should work
