---------------------------------------

             Summary: Marshaller mappings to be stored in a separate subfolder for each Ignite
node
                 Key: IGNITE-7635
                 URL: https://issues.apache.org/jira/browse/IGNITE-7635
             Project: Ignite
          Issue Type: Improvement
            Reporter: Sergey Chugunov


Current implementation of persisting marshaller mappings in FS may cause issues (e.g. see
this [question|http://apache-ignite-users.70518.x6.nabble.com/MarshallerContextImpl-Failed-to-write-class-name-to-file-td18439.html]
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.
