>                 Key: SPARK-11356
>                 URL: https://issues.apache.org/jira/browse/SPARK-11356
>             Project: Spark
>          Issue Type: Improvement
>          Components: SQL
>    Affects Versions: 1.5.1
>            Reporter: Maciej Bryński
>
> I have two apps:
> 1) First one periodically append data to parquet (which creates new partition)
> 2) Second one executes query on data
> Right now I can't find any possibility to force Spark to make partition discovery. So every query is executed on the same data.
> I tried --conf spark.sql.parquet.cacheMetadata=false but without success.
> Is there any option to make this happen ?
> App 1 - periodically (eg. every hour)
> {code}
> df.write.partitionBy("day").mode("append").parquet("some_location")
> {code}
> App 2 - example
> {code}
> sqlContext.read.parquet("some_location").registerTempTable("t")
> sqlContext.sql("select * from t where day = 20151027").count()
> {code}
