java.lang.InternalError: Malformed class name when using custom class as an indexedType

[manuelmourato <ma...@gmail.com>]

 Hi there.
 I am trying to create a cache configuration so that I can later use it in
an IgniteContext using the ignite-spark module.
 This is the code I used to create the cache cofig:

   val ignConf:IgniteConfiguration= new IgniteConfiguration()
    case class Sensor_Att(
                           @(QuerySqlField @field)(index = true)  a: String,
                           b: String,
                           c: String,
                           d:List[String],
                           e:List[List[List[String]]],
                            f:String,
                            g:String
                         ) 
    val cacheCfg:CacheConfiguration[String,Sensor_Att]=new
CacheConfiguration[String,Sensor_Att]()
    cacheCfg.setIndexedTypes(classOf[String],classOf[Sensor_Att])
    cacheCfg.setName("test")

 This returns the following error when I run it:

[error] (run-main-0) java.lang.InternalError: Malformed class name
java.lang.InternalError: Malformed class name
	at java.lang.Class.getSimpleName(Class.java:1330)

If I replace the class SensorAtt by String (for example) in cacheCfg, this
error doesn't appear, so I assume it must be an issue with this custom
class.

Any ideas on how I can use a user created class like this when creating a
cache config?

 Thanks.
 Cheers
