------------------------------------

             Summary: Changing Hadoop parameter through 
sparkSession.sparkContext.hadoopConfiguration doesn't work
                 Key: SPARK-18017
                 URL: https://issues.apache.org/jira/browse/SPARK-18017
             Project: Spark
          Issue Type: Bug
    Affects Versions: 2.0.0
         Environment: Scala version 2.11.8; Java 1.8.0_91; 
com.databricks:spark-csv_2.11:1.2.0
            Reporter: Yuehua Zhang


My Spark job tries to read csv files on S3. I need to control the number of 
partitions created so I set Hadoop parameter fs.s3n.block.size. However, it 
stopped working after we upgrade Spark from 1.6.1 to 2.0.0. Not sure if it is 
related to https://issues.apache.org/jira/browse/SPARK-15991.
