Getting null query output after using QueryEntity - ignite

Question

I have written following query entity for my database. I provide this file to ignite server node for index mapping. Loading part of data is done through ignite client node.

All entries of this warehouse table gets loaded correctly(verified using ignitevisorcmd.sh). For this query entity I have created jar file of package schema, which contains warehouse class. I kept this jar file in libs folder in apache ignite installation path. When I run query against this warehouse table, I am getting null output. Why is this happening?

Answer 1

The value type in configuration looks suspicious:
<property name="valueType" value="schema.warehouse"/>
Make sure that this value is correct value class name. Also what query are you executing?
