Remus Rusanu commented on HIVE-5845:
------------------------------------
The uploaded fix addresses all the issues I found:
- changes the OrcStruct serialization to use the correct object inspector (the
one that writes into the OrcStruct fields)
- the VectorExpressionWriterFactory was refactored to handle all
assignments/writes and new object creation via the object inspectors, rather
than assumming Writable types
- a new API is available on the VectorExpressionWritter: setValue, which
writes the value into the passed in object rather that returning a mutated the
per-writer singleton. This was necessary for the OrcStruct vector
serialization, which would end up reusing the same instance on all rows in the
vector otherwise
- changed the VectorExpressionWriter to use TypeInfo Category and
PrimitiveCategory rather than type name string comparison
- Have the VectorExpressionWriter generate writers from ObjectInspector and
derive the OI from ExprNodeDesc rather than the other way around
- extended the TestVectorExpressionWriter unit tests to cover the setValue API
and struct fields assignment
