When elastic instance start is attempted, I see exception as -
[2020-12-11T10:12:32,933][WARN ][o.e.i.m.MapperService ] [fully-qualified-host-name] [.kibana_1] [[.kibana_1/9r8cU43FQlWzDMRvN-dxHA]] failed to apply mappings org.elasticsearch.index.mapper.MapperParsingException: Failed to parse mapping [_doc]: No handler for type [flattened] declared on field [local_metadata]
I am using OSS rpm for 7.10.1.
Is this a known issue? Please let me know. Thanks.
