Jianshi Huang created SPARK-3845:
------------------------------------
Summary: SQLContext(...) should inherit configurations from
SparkContext
Key: SPARK-3845
URL: https://issues.apache.org/jira/browse/SPARK-3845
Project: Spark
Issue Type: Improvement
Components: SQL
Affects Versions: 1.1.0
Reporter: Jianshi Huang
It's very confusing that Spark configurations (e.g. spark.serializer,
spark.speculation, etc.) can be set in the spark-default.conf file, while
SparkSQL configurations (e..g spark.sql.inMemoryColumnarStorage.compressed,
spark.sql.codegen, etc.) has to be set either in sqlContext.setConf or sql("SET
...").
When I do:
val sqlContext = new org.apache.spark.sql.SQLContext(sparkContext)
I would expect sqlContext recognizes all the SQL configurations comes with
sparkContext.
