Pavel Kuznetsov commented on IGNITE-11919:
------------------------------------------

As [~sergey-chugunov] added we also need to recommend to delete the "binary_meta" directory which contains info about binary fields.

> Follow this discussion thread to find out the reason for the change:
> http://apache-ignite-developers.2346864.n4.nabble.com/Ignite-stops-working-suddenly-during-dev-td42207.html
> It's suggested to apply the following format:
> {code}
> ERROR: Type 'ClassName/TypeName' has a different/incorrect type
> for field 'FieldName'. Expected 'type1' but 'type2' was provided. Field
> type's modification is unsupported, clean {root_path}/marshaller directory
> if the type change is required.
> {code}
> That's an example of how it will look like:
> {code}
> ERROR: Type 'Person' has a different/incorrect type
> for field 'salary'. Expected 'double' but 'string' was provided. Field
> type's modification is unsupported, clean {root_path}/marshaller directory
> if the type change is required.
> {code}
