Assignee: Michael Armbrust
> Spark SQL ignores split.size
> ----------------------------
>
> Key: SPARK-18211
> URL: https://issues.apache.org/jira/browse/SPARK-18211
> Project: Spark
> Issue Type: Bug
> Components: SQL
> Affects Versions: 2.0.0
> Reporter: lostinoverflow
> Assignee: Michael Armbrust
>
> I expect that RDD and DataFrame will have the same number of partitions
> (worked in 1.6) but it looks like Spark SQL ignores Hadoop configuration.
> {code}
> import org.apache.spark.sql.SparkSession
> object App {
> def main(args: Array[String]) {
> val spark = SparkSession
> .builder()
> .master("local[*]")
> .appName("split size")
> .getOrCreate()
> spark.sparkContext.hadoopConfiguration.setInt("mapred.min.split.size",
> args(0).toInt)
> spark.sparkContext.hadoopConfiguration.setInt("mapred.max.split.size",
> args(0).toInt)
> println(spark.sparkContext.textFile(args(1)).partitions.size)
> println(spark.read.textFile(args(1)).rdd.partitions.size)
> spark.stop()
> }
> }
