-------------------------------------
Summary: Fix JDBCOptions.asConnectionProperties to be
case-insensitive
Key: SPARK-18419
URL: https://issues.apache.org/jira/browse/SPARK-18419
Project: Spark
Issue Type: Bug
Components: SQL
Reporter: Dongjoon Hyun
Priority: Minor
`JDBCOptions.asConnectionProperties` fails to filter `CaseInsensitiveMap`
correctly. For the following case, it returns `Map('numpartitions' -> "10")` as
a wrong result.
{code}
val options = new JDBCOptions(new CaseInsensitiveMap(Map(
"url" -> "jdbc:mysql://localhost:3306/temp",
"dbtable" -> "t1",
"numPartitions" -> "10")))
assert(options.asConnectionProperties.isEmpty)
{code}
