> Hi, it's my first Jira and I don't know how to make patches, so I'll explain the issue in the description as it is rather simple.
> I have a problem serializing "DefaultHCatRecord" using Apache Flink when those records include Timestamps because of an incorrect class cast in org.apache.hadoop.hive.serde2.io.TimestampWritable.write(DataOutput out). It is implemented using a cast to Outputstream  : 
> public void write(DataOutput out) throws IOException {
>     write((OutputStream) out);
>  }
> but nothing says that a DataOutput object is an OutputStream, (and it's not the case in Flink) it should rather be implmented using the same code as write(OutputStream) :
> {
> checkBytes();
> out.write(currentBytes, offset, getTotalLength());
> }
