> AssertionError in CDC on metadata deserialize
> ---------------------------------------------
>
> Key: IGNITE-20572
> URL: https://issues.apache.org/jira/browse/IGNITE-20572
> Project: Ignite
> Issue Type: Bug
> Reporter: Sergey Korotkov
> Assignee: Maksim Timonin
> Priority: Major
> Labels: ise
> Time Spent: 10m
> Remaining Estimate: 0h
>
> CDC process terminates sometimes with the below error.
> One the cases is cache creation which causes the creation of the .bin file in
> the binary_meta directory. Say if custom indexed types are passed via the
> CacheConfiguration.setIndexedTypes.
> Looks like the race condition. CDC processed the binary meta file which is
> already created but still empty.

> The same way as in the MarshallerMappingFileStore.writeMapping using the
