Review Comment:
One workaround might be:
```scala
val config = new HadoopMapReduceWriteConfigUtil[K, V](new
SerializableConfiguration(conf)) {
override def createCommitter(jobId: Int):
HadoopMapReduceCommitProtocol = {
FileCommitProtocol.instantiate(
className = "CustomClassName",
jobId = jobId.toString,
outputPath = new SerializableConfiguration(
conf).value.get("mapreduce.output.fileoutputformat.outputdir")
).asInstanceOf[HadoopMapReduceCommitProtocol]
}
}
SparkHadoopWriter.write(
rdd = self,
config = config)
```
Although `HadoopMapReduceWriteConfigUtil` would have to be inherited within
`org.apache.spark` package in your project though (if you're using Scala). For
Java, it won't validate the package name.
