[jira] [Issue Comment Deleted] (SPARK-12288) Support UnsafeRow in Coalesce/Except/Intersect

["Xiao Li (JIRA)" <ji...@apache.org>]

Xiao Li updated SPARK-12288:
----------------------------
    Comment: was deleted

(was: [~davies] It sounds like Except and Intersect can support UnsafeRow? 

We just need to add the following line to Except and Intersect
{code}
override def outputsUnsafeRows: Boolean = children.forall(_.outputsUnsafeRows)
override def canProcessUnsafeRows: Boolean = true
override def canProcessSafeRows: Boolean = true
{code}

Is my understanding correct?

Thanks!)
