             Summary: DataFrame.drop(colName) fails if another column has a period in its name
                 Key: SPARK-16210
                 URL: https://issues.apache.org/jira/browse/SPARK-16210
             Project: Spark
          Issue Type: Bug
          Components: SQL
    Affects Versions: 1.6.1
         Environment: Spark 1.6.1 on Databricks
            Reporter: Simeon Simeonov


The following code fails with {{org.apache.spark.sql.AnalysisException: cannot resolve 'x.y' given input columns: [abc, x.y]}} because of the way {{drop()}} uses {{select()}} under the covers.

{code}
val rdd = sc.makeRDD("""{"x.y": 5, "abc": 10}""" :: Nil)
sqlContext.read.json(rdd).drop("abc")
{code}
