Subject [jira] [Commented] (SPARK-8653) Add constraint for Children expression for data type
Date Wed, 01 Jul 2015 06:18:04 GMT

Reynold Xin commented on SPARK-8653:
------------------------------------

I'm not opposed to the idea, but we have already implemented almost all of them already. I
don't think it is a clear cut that it is better to have those in the expressions.

> Currently, we have trait in Expression like `ExpectsInputTypes` and also the `checkInputDataTypes`,
but can not convert the children expressions automatically, except we write the new rules
in the `HiveTypeCoercion`.
