Sean R. Owen updated SPARK-43439:
---------------------------------
Priority: Minor (was: Major)
> Drop does not work when passed a string with an alias
> -----------------------------------------------------
>
> Key: SPARK-43439
> URL: https://issues.apache.org/jira/browse/SPARK-43439
> Project: Spark
> Issue Type: Bug
> Components: PySpark
> Affects Versions: 3.4.0
> Reporter: Frederik Paradis
> Priority: Minor
>
> When passing a string to the drop method, if the string contains an alias,
> the column is not dropped. However, passing a column object with the same
> name and alias, it works.
> {code:python}
> from pyspark.sql import SparkSession
> import pyspark.sql.functions as F
> spark =
> SparkSession.builder.master("local[1]").appName("local-spark-session").getOrCreate()
> df = spark.createDataFrame([(1, 10)], ["any", "hour"]).alias("a")
> j = df.drop("a.hour")
> print(j) # DataFrame[any: bigint, hour: bigint]
> jj = df.drop(F.col("a.hour"))
> print(jj) # DataFrame[any: bigint]
> {code}
