Vadim Pakhnushev updated IGNITE-23825:
--------------------------------------
Description:
When ComputeJob started from the client on remote node returns a Tuple returned
from Table API directly, client handler node fails to unmarshal it:
{noformat}
Caused by:
org.apache.ignite.internal.network.serialization.marshal.UnmarshalException:
Cannot instantiate org.apache.ignite.internal.table.TableRow$ValueRowChunk

{noformat}
The reason is we use user objects serialization to pass job result between
nodes and there are two problems there:
* {{ClassDescriptorFactory}} doesn't search for the {{writeReplace}} method in
superclasses.
* {{TupleImpl}} doesn't declare {{writeObject}} so the
{{StructuredObjectMarshaller.fillStructuredObjectLayerFrom}} method doesn't
call {{readObject}} to properly deserialize it.

The reason is we use Java serialization to pass job result between nodes and
TableRow$ValueRowChunk is not serializable.
