Tien-Dung LE updated SPARK-9280:
--------------------------------
Description:
In a spark session, stopping a spark context and create a new spark context and
hive context does not clean the spark sql configuration. More precisely, the
new hive context still keeps the previous configuration settings. It would be
great if someone can let us know how to avoid this situation.
{code:title=New hive context should not load the configurations from history}
sqlContext.setConf( "spark.sql.shuffle.partitions", "10")
sc.stop
val sparkConf2 = new org.apache.spark.SparkConf()
val sc2 = new org.apache.spark.SparkContext( sparkConf2 )
val sqlContext2 = new org.apache.spark.sql.hive.HiveContext( sc2 )
sqlContext2.getConf( "spark.sql.shuffle.partitions", "20")
// got 20 as expected
sqlContext2.setConf( "foo", "foo")
sqlContext2.getConf( "spark.sql.shuffle.partitions", "30")
// expected 30 but got 10
{code}
