---------------------------------

             Summary: CaseInsensitiveMap throws "java.io.NotSerializableException"
                 Key: SPARK-5141
                 URL: https://issues.apache.org/jira/browse/SPARK-5141
             Project: Spark
          Issue Type: Bug
          Components: SQL
            Reporter: Gankun Luo
            Priority: Minor


The following code throws a serialization.[https://github.com/luogankun/spark-jdbc|https://github.com/luogankun/spark-jdbc]

{code}
CREATE TEMPORARY TABLE jdbc_table
USING com.luogankun.spark.jdbc
OPTIONS (
sparksql_table_schema  '(TBL_ID int, TBL_NAME string, TBL_TYPE string)',
jdbc_table_name    'TBLS',
jdbc_table_schema '(TBL_ID , TBL_NAME , TBL_TYPE)',
url    'jdbc:mysql://hadoop000:3306/hive',
user    'root',
password    'root'
);

select TBL_ID,TBL_ID,TBL_TYPE from jdbc_table;
{code}

I get the following stack trace:
