Artem Shutak commented on IGNITE-2191:
--------------------------------------
The issue at point 2 has been discussed with Alexey G. and Vladimir. As a
result, it was decided to add {{BinaryNameMapper}} property to
{{BinaryConfiguration}} (as we already have for .Net).
The new property implemented. As a result, all .Net tests pass. Will fix java
tests and new tests for the property.
> Binary marshaller: support user classes with the same simple name

> Key: IGNITE-2191
> URL: https://issues.apache.org/jira/browse/IGNITE-2191
> Project: Ignite
> Issue Type: Bug
> Components: cache
> Affects Versions: ignite-1.4
> Reporter: Denis Magda
> Assignee: Artem Shutak
> Priority: Critical
> Labels: important
> Fix For: 1.6
>
>
> Presently the user won't be able to use across the cluster object that have a
> single simple name.
> As an example if the user has 'org.comp.MyObject' and
> 'org.apache.comp.MyObject' then he won't be able to have them both in a
> cluster because marshalling mechanism supports uniqueness at simple name
> level only.
> There are several reasons for that:
> - interoperability with other platforms;
> - queries that use simple name is their 'where' clause.
> In general according to the API as a workaround the user can implement its
> own BinaryIdMapper returning a precise id for every class. However there is a
> bug in BinaryContext that passes simple name rather than a full name to a
> BinaryIdMapper implementation. BinaryIdMapper must be fixed as well.
