Yin Huai created SPARK-3641:
-------------------------------
Summary: Correctly populate SparkPlan.currentContext
Key: SPARK-3641
URL: https://issues.apache.org/jira/browse/SPARK-3641
Project: Spark
Issue Type: Bug
Components: SQL
Affects Versions: 1.1.0
Reporter: Yin Huai
Priority: Critical
After creating a new SQLContext, we need to populate SparkPlan.currentContext
before we create any SparkPlan. Right now, only SQLContext.createSchemaRDD
populate SparkPlan.currentContext. SQLContext.applySchema is missing this call
and we can have NPE as described in
http://qnalist.com/questions/5162981/spark-sql-1-1-0-npe-when-join-two-cached-table.
