----------------------------------

             Summary: org.apache.hadoop.hive.serde2.io.TimestampWritable.write(DataOutput
out) makes incorrect cast
                 Key: HIVE-11339
                 URL: https://issues.apache.org/jira/browse/HIVE-11339
             Project: Hive
          Issue Type: Bug
          Components: Serializers/Deserializers
    Affects Versions: 0.14.0
            Reporter: Arnaud Linz


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());
}
