Dongjoon Hyun commented on SPARK-17053:
---------------------------------------
Oh, I see what you mean. Yes, indeed. Currently, Spark ignores the option.
{code}
scala> sql("set hive.exec.drop.ignorenonexistent=true")
res1: org.apache.spark.sql.DataFrame = [key: string, value: string]
scala> sql("drop table a")
org.apache.spark.sql.AnalysisException: Table to drop '`a`' does not exist;
{code}
I'll make a PR soon. Could you update the title more specifically?
> DROP statement should not require IF EXISTS

> Key: SPARK-17053
> URL: https://issues.apache.org/jira/browse/SPARK-17053
> Project: Spark
> Issue Type: Bug
> Components: SQL
> Affects Versions: 2.0.0
> Reporter: Gokhan Civan
>
> In version 1.6.1, the following does not throw an exception:
> create table a as select 1; drop table a; drop table a;
> In version 2.0.0, the second drop fails; this is not compatible with Hive.
> The same problem exists for views.
