Question

Hi all,
I met a problem for the EID2.3, when i follow the video step by step, which provided by the OTN
Getting started with Endeca Information Discovery , Part 2 :Loading and Viewing Data, 2.2 - Load one Data Source via Integrator
I met a error after run the graph.
Could anyone tell me what does this mean?
*ERROR [SocketReader] - Received error message from server: Record put for property "FactSales_OrderQuantity" must have an assignment in property "mdex-property_Type"*_
Thanks in advance!
Best Regards,

Answer 1

This error is saying that a user create attribute "FactSales_OrderQuantity" is missing a system property "mdex-property_Type". These system properties are how the index defines the user attributes and when one is missing, in this case the type, the mdex does not know how to handle the incoming data for the attribute. In this case I believe the problem is cause by having the "Reset Data Store" component in the same phase as the "Bulk Load to Data Store". The Reset data store tells the index to delete all records and to clear all the attribute's metadata (properties). Since this graph is also trying to load data via the bulk load while at the same time resetting the index and all the system properties.
To resolve this issue you should have the reset component in a separate phase, or a graph all to itself so it always executes in isolation.
