> 'already exists' if table foo exists
> ---------------------------------------------------------------------------------------------------------------------
>
> Key: SPARK-28633
> URL: https://issues.apache.org/jira/browse/SPARK-28633
> Project: Spark
> Issue Type: Bug
> Components: Spark Core
> Affects Versions: 2.4.3
> Reporter: Chris Bedford
> Priority: Major
>
> I am guessing the bug title will be sufficient explanation of the issue.
> below is a little script to illustrate. Running the script gives this error:
> > org.apache.spark.sql.AnalysisException: Table `example` already exists.;
> spark.sql("drop table if exists example ").show()
> case class Person(first: String, last: String, age: Integer)
> val df = List(
> Person("joe", "x", 9),
> Person("fred", "z", 9)).toDF()
> df.write.option("mode","overwrite").saveAsTable("example")
> val recover1 = spark.read.table("example")
> recover1.show()
> val df3 = List(
> Person("mouse", "x", 9),
> Person("golf", "z", 9)).toDF()
> df3.write.option("mode","overwrite").saveAsTable("example")
> val recover4 = spark.read.table("example")
> recover4.show()
