I am seeing strange warnings (see below) when putting mappings containing 'dynamic\_templates'. The mapping seems perfectly right and if you closely look at the warning below you find that only the order of the 'match' and 'match\_mapping\_type' is different. Content wise the mappings are the same. Is this a bug in Elastic Search? Is there anything I can do on my end to avoid the warning (as it is badly spamming my log files)? 2011-03-08 16:00:34,006 WARN [elasticsearch[Fagin]clusterService#updateTask-pool-11-thread-1] [org.elasticsearch.indices.cluster] [] - [Fagin] [test\_index] parsed mapping [test\_type], and got different sources original: {"test\_type":{"dynamic\_templates":[{"template1":{"mapping": {"index":"not\_analyzed","type":"string"},"match\_mapping\_type":"string","match":"_"}}],"properties": {}}} parsed: {"test\_type":{"dynamic\_templates":[{"template1":{"mapping": {"index":"not\_analyzed","type":"string"},"match":"_","match\_mapping\_type":"string"}}],"properties": {}}} ---

Heya, Its not something that breaks the system, its just a warning that extra processing of mapping is done (which should not really be done). I simply need to fix it (the warning is there so if I miss something, it will bubble up through the users ๐Ÿ™‚ ). Can you gist a recreation of this so it will be simpler for me to fix it?
