Description

Current implementation of persisting marshaller mappings in FS may cause issues (e.g. see this question on user list) when two or more nodes are started on the same machine in the same work directory (IgniteConfiguration::setWorkDirectory).

There is no such problem with persisted Binary Metadata as each node creates separate subfolder under the <workDir>/binary_meta folder.

The same approach can be implemented for marshaller mappings too.
