What is "java.sql.SQLException: Unsupported type -101"?

[Sambit Tripathy (RBEI/EDS1)]

Hi,

I was trying to get a oracle table using JDBC datasource

val jdbcDF = sqlContext.load("jdbc", Map( "url" -> 
"jdbc:oracle:thin:USER/p...@host.com:1517:sid", "dbtable" -> 
"USER.TABLE","driver" -> "oracle.jdbc.OracleDriver"))

and got the error below

java.sql.SQLException: Unsupported type -101

Any idea what it could be?
