> Attempting to write to a HCatalog defined table backed by the AvroSerde fails with the
following stacktrace:
> {code}
> java.lang.ClassCastException: org.apache.hadoop.io.NullWritable cannot be cast to org.apache.hadoop.io.LongWritable
> 	at org.apache.hadoop.hive.ql.io.avro.AvroContainerOutputFormat$1.write(AvroContainerOutputFormat.java:84)
> 	at org.apache.hcatalog.mapreduce.FileRecordWriterContainer.write(FileRecordWriterContainer.java:253)
> 	at org.apache.hcatalog.mapreduce.FileRecordWriterContainer.write(FileRecordWriterContainer.java:53)

> 	at org.apache.hadoop.mapreduce.task.TaskInputOutputContextImpl.write(TaskInputOutputContextImpl.java:85)
> {code}
> The proximal cause of this failure is that the AvroContainerOutputFormat's signature
mandates a LongWritable key and HCat's FileRecordWriterContainer forces a NullWritable. I'm
not sure of a general fix, other than redefining HiveOutputFormat to mandate a WritableComparable.
> It looks like accepting WritableComparable is what's done in the other Hive OutputFormats,
and there's no reason AvroContainerOutputFormat couldn't also be changed, since it's ignoring
the key. That way fixing things so FileRecordWriterContainer can always use NullWritable could
get spun into a different issue?
> The underlying cause for failure to write to AvroSerde tables is that AvroContainerOutputFormat
doesn't meaningfully implement getRecordWriter, so fixing the above will just push the failure
into the placeholder RecordWriter.
