Access to generic type static method in scala

I am trying to save some Spark RDDs to HDFS using an Avro format. At the moment, I have a trait that defines two methods:

import org.apache.avro.specific.SpecificRecordBase
trait MyTrait {
  type T <: SpecificRecordBase

  def getData(): RDD[(AvroKey[T], NullWritable)] // overridden in other objects

  def write(data: RDD[(AvroKey[T], NullWritable)]) = {
    // ... 
    val job = Job.getInstance(...)
    job.setOutputFormatClass(classOf[AvroKeyOutputFormat[T]])
    AvroJob.setOutputKeySchema(job, T.SCHEMA$) // how to do this?
    data saveAsNewAPIHadoopFile ( 
      outputDirectory,
      classOf[AvroKey[T]],
      classOf[NullWritable],
      classOf[AvroKeyOutputFormat[T]],
      job.getConfiguration
    )
  }
}

Each object extending the trait MyTrait will override the type T (according to the schema it will be use) and the method getData.

I am stuck on the line

AvroJob.setOutputKeySchema(job, T.SCHEMA$) // how to do this?

It doesn't compile. I have read the Scala Reflection documentation page, but it's not 100% clear to me how I can use it, in order to access a static method (I could use the method .getSchema as well, but it just doesn't work).
