Setting row group size in hdfs












0















I'm trying to set both the block size and the row group size for my hdfs instance for testing. I went in spark-shell and did the following:



scala> spark.sparkContext.hadoopConfiguration.get("dfs.block.size")

res1: String = 134217728



scala> spark.sparkContext.hadoopConfiguration.get("parquet.block.size")

res1: String = null


I'm wondering if I got the name wrong for the row group size, or it's different in the version of hadoop I'm using (2.7). I got the name from here: http://ingest.tips/2015/01/31/parquet-row-group-size/






apache-spark hadoop hdfs parquet
