------------------------------------
Summary: EquivalentExpressions throw IllegalStateException
Key: SPARK-46632
URL: https://issues.apache.org/jira/browse/SPARK-46632
Project: Spark
Issue Type: Bug
Components: Optimizer, Spark Core, SQL
Affects Versions: 3.5.0, 3.4.0, 3.3.0
Reporter: zhangzhenhao
EquivalentExpressions throw IllegalStateException with some IF expresssion
```scala
import org.apache.spark.sql.catalyst.dsl.expressions.DslExpression
import org.apache.spark.sql.catalyst.expressions.\{EquivalentExpressions, If,
Literal}
import org.apache.spark.sql.functions.col
val one = Literal(1.0)
val y = col("y").expr
val e1 = If(
Literal(true),
y * one * one + one * one * y,
y * one * one + one * one * y
)
(new EquivalentExpressions).addExprTree(e1)
```
result is
```
java.lang.IllegalStateException: Cannot update expression: (1.0 * 1.0) in map:
Map(ExpressionEquals(('y * 1.0)) -> ExpressionStats(('y * 1.0))) with use
count: -1
