Summary: java.io.NotSerializableException:
org.apache.spark.sql.SQLConf
Key: SPARK-5235
URL: https://issues.apache.org/jira/browse/SPARK-5235
Project: Spark
Issue Type: Bug
Reporter: Alex Baretta
The SQLConf field in SQLContext is neither Serializable nor transient. Here's
the stack trace I get when running SQL queries against a Parquet file.
Exception in thread "Thread-43" org.apache.spark.SparkException: Job aborted
due to stage failure: Task not serializable: java.io.NotSerializableException:
