> Key: SPARK-5839
> URL: https://issues.apache.org/jira/browse/SPARK-5839
> Project: Spark
> Issue Type: Bug
> Components: SQL
> Reporter: Yin Huai
> Priority: Blocker
>
> For example, when we run
> {code}
> val originalDefaultSource = conf.defaultDataSourceName
> val rdd = sparkContext.parallelize((1 to 10).map(i => s"""{"a":$i,
> "b":"str${i}"}"""))
> val df = jsonRDD(rdd)
> conf.setConf(SQLConf.DEFAULT_DATA_SOURCE_NAME, "org.apache.spark.sql.json")
> // Save the df as a managed table (by not specifiying the path).
> df.saveAsTable("savedJsonTable")
> checkAnswer(
> sql("SELECT * FROM savedJsonTable tmp where tmp.a > 5"),
> df.collect())
> // Drop table will also delete the data.
> sql("DROP TABLE savedJsonTable")
> conf.setConf(SQLConf.DEFAULT_DATA_SOURCE_NAME, originalDefaultSource)
> {code}
> We will get
> {code}
> query with predicates *** FAILED *** (85 milliseconds)
