Jianshi Huang commented on SPARK-3845:
--------------------------------------
Looks like it's fixed in latest 1.2.0 snapshot.
In 1.1.0, sqlContext.getAllConfs returns empty map.

> 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.
