Yanbo Liang updated SPARK-17986:
--------------------------------
Affects Version/s: (was: 2.0.1)
> SQLTransformer leaks temporary tables
> -------------------------------------
>
> Key: SPARK-17986
> URL: https://issues.apache.org/jira/browse/SPARK-17986
> Project: Spark
> Issue Type: Bug
> Components: ML
> Reporter: Drew Robb
> Assignee: Drew Robb
> Priority: Minor
> Fix For: 2.0.2, 2.1.0
>
>
> The SQLTransformer creates a temporary table when called, and does not delete
> this temporary table. When using a SQLTransformer in a long running Spark
> Streaming task, these temporary tables accumulate.
> I believe that the fix would be as simple as calling
> `dataset.sparkSession.catalog.dropTempView(tableName)` in the last part of
> `transform`:
> https://github.com/apache/spark/blob/v2.0.1/mllib/src/main/scala/org/apache/spark/ml/feature/SQLTransformer.scala#L65.
