Apache Spark reassigned SPARK-18335:
------------------------------------
Assignee: (was: Apache Spark)
> Add a numSlices parameter to SparkR's createDataFrame
> -----------------------------------------------------
>
> Key: SPARK-18335
> URL: https://issues.apache.org/jira/browse/SPARK-18335
> Project: Spark
> Issue Type: Improvement
> Components: SparkR
> Reporter: Shixiong Zhu
>
> SparkR's createDataFrame doesn't have a `numSlices` parameter. The user
> cannot set a partition number when converting a large R dataframe to SparkR
> dataframe. A workaround is using `repartition`, but it requires a shuffle
> stage. It's better to support the `numSlices` parameter in the
> `createDataFrame` method.
