Hi all, I'm testing delete mapping for types, but in a certain time i get shard failure error. 1 shard goes to unassigned shard. Scenario is like below: - put mappings for 15 different types - insert a couple of docs with 3 test fields for each types - delete all the mappings - repeat above test code again and again until i get the shard error you may refer the code here. [https://gist.github.com/mintbass/5675355](https://gist.github.com/mintbass/5675355) The error occured because 'no index mapper found for field' at org.elasticsearch.index.codec.PerFieldMappingPostingFormatCodec class. So, i modified a class to return the defaultPostingFormat value not to throw an exception in org.elasticsearch.index.codec.PerFieldMappingPostingFormatCodec. ``` @Override public PostingsFormat getPostingsFormatForField(String field) { final FieldMappers indexName = mapperService.indexName(field); if (indexName == null) { //throw new ElasticSearchIllegalStateException("no index mapper ``` found for field: [" + field + "]"); return defaultPostingFormat; } PostingsFormatProvider postingsFormat = indexName.mapper().postingsFormatProvider(); return postingsFormat != null ? postingsFormat.get() : defaultPostingFormat; } Is there any workaround to avoid this? Could it be any problem the code i changed in the future? so far, i don't see any problem. Thanks -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.

May be you should wait for a Yellow cluster status after each cluster change call (remove index, create index, delete mapping...). Could it help? -- David 😉 Twitter : @dadoonet / @elasticsearchfr / @scrutmydocs Le 30 mai 2013 à 06:39, Marcus Park [mintbass@gmail.com](mailto:mintbass@gmail.com) a écrit : Hi all, I'm testing delete mapping for types, but in a certain time i get shard failure error. 1 shard goes to unassigned shard.
