Tim Armstrong created SPARK-34857:
-------------------------------------
Summary: AtLeastNNonNulls does not show up correctly in explain
Key: SPARK-34857
URL: https://issues.apache.org/jira/browse/SPARK-34857
Project: Spark
Issue Type: Bug
Components: SQL
Affects Versions: 3.1.1
Environment: I see this in an explain plan
{noformat}
(12) Filter
Input [3]: [c1#2410L, c2#2419, c3#2422]
Condition : AtLeastNNulls(n, c1#2410L)
I expect it to be AtLeastNNonNulls and n to have the actual value.
{noformat}
Proposed fix is to change
https://github.com/databricks/runtime/blob/09ad623c458c40cbaa0dbb4b9f600d96531d35f5/sql/catalyst/src/main/scala/org/apache/spark/sql/catalyst/expressions/nullExpressions.scala#L384
to
{noformat}
override def toString: String = s"AtLeastNNonNulls(${n},
${children.mkString(",")})"
{noformat}
Or maybe it's OK to remove and use a default implementation?
