> Handling ignoreIfExists in HiveExternalCatalog createTable API
> --------------------------------------------------------------
>
> Key: SPARK-18595
> URL: https://issues.apache.org/jira/browse/SPARK-18595
> Project: Spark
> Issue Type: Improvement
> Components: SQL
> Affects Versions: 2.0.2
> Reporter: Xiao Li
>
> Currently, `HiveExternalCatalog`'s `createTable` issues the exception if
> `ignoreIfExists` is true and the table exists. However, this is just a
> partial handling of `ignoreIfExists`. We can cover the other cases too.
> Instead of passing `ignoreIfExists` of CREATE TABLE to Hive metastore, we can
> handle it in `HiveExternalCatalog`'s `createTable`.
