Which HBase version are you using ?

Can you show the full stack trace ?

can anyone please give me some help how to write custom converter of hbase data to (for example) tuples of ((family, qualifier, value), ) for pyspark:

I was trying something like (here trying to tuples of ("family:qualifier:value", )):

class HBaseResultToTupleConverter extends Converter[Any, List[String]] {
  override def convert(obj: Any): List[String] = {
    val result = obj.asInstanceOf[Result]
    result.rawCells().map(cell => List(Bytes.toString(CellUtil.cloneFamily(cell)),

but then I get a error:

14/12/22 16:27:40 WARN python.SerDeUtil:
Failed to pickle Java object as value: $colon$colon, falling back
to 'toString'. Error: couldn't introspect javabean: java.lang.IllegalArgumentException: wrong number of arguments

does anyone have a hint?
