After update from Elasticsearch 2.1 to 5.6 got this error in Elasticsearch log:
java.lang.IllegalArgumentException: Mapper for [kibanaSavedObjectMeta.searchSourceJSON] conflicts with existing mapping in other types:
[mapper [kibanaSavedObjectMeta.searchSourceJSON] is used by multiple types. Set update_all_types to true to update [fielddata] across all types.]
at org.elasticsearch.index.mapper.FieldTypeLookup.checkCompatibility(FieldTypeLookup.java:130) ~[elasticsearch-5.6.0.jar:5.6.0]
Did it generate a bad mapping during upgrade?
