----------------------------------------

             Summary: NOT condition working incorrectly
                 Key: SPARK-22307
                 URL: https://issues.apache.org/jira/browse/SPARK-22307
             Project: Spark
          Issue Type: Bug
          Components: Spark Core
    Affects Versions: 2.1.1, 2.1.0
            Reporter: Andrey Yakovenko


Suggest test case: table with x record filtered by expression expr returns y records (< x), not(expr) does not returns x-y records. Work around: when(expr, false).otherwise(true) is working fine.

val ctg = spark.sqlContext.read.json("/user/Catalog.json")
scala> ctg.printSchema

val col1 = expr("((((Id IN ('13MXIIAA4', '13MXIBAA4')) OR (Parent.Id IN ('13MXIIAA4', '13MXIBAA4'))) OR (Parent.Parent.Id IN ('13MXIIAA4', '13MXIBAA4'))) OR (Parent.Parent.Parent.Id IN ('13MXIIAA4', '13MXIBAA4')))")
col1: org.apache.spark.sql.Column = ((((Id IN (13MXIIAA4, 13MXIBAA4)) OR (Parent.Id IN (13MXIIAA4, 13MXIBAA4))) OR (Parent.Parent.Id IN (13MXIIAA4, 13MXIBAA4))) OR (Parent.Parent.Parent.Id IN (13MXIIAA4, 13MXIBAA4)))

scala> ctg.count
res5: Long = 623

scala> ctg.filter(col1).count
res2: Long = 2

scala> ctg.filter(not(col1)).count
res3: Long = 4

scala> ctg.filter(when(col1, false).otherwise(true)).count
res4: Long = 621
{code}
Table is hierarchy like structure and has a records with different number of levels filled up. I have a suspicion that due to partly filled hierarchy condition return null/undefined/failed/nan some times (neither true or false).
