Hi All,
I am using PostgreSQL database. I am using the following jdbc call to
access a customer table (*customer_id int, event text, country text,
content xml)* in my database.
*val dataframe1 = sqlContext.load("jdbc", Map("url" ->
"jdbc:postgresql://localhost/customerlogs?user=postgres&password=postgres",
"dbtable" -> "customer"))*
When i run above command in spark-shell i receive the following error.
*java.sql.SQLException: Unsupported type 1111*

Is xml column type not supported yet in spark ? is there any way to fix

Thanks,
