hey all, I have a problem, I put data into elastic type geo\_point but the data had value "NaN, NaN" and 999,999. I get an error like :  
'''  
type: 'mapper\_parsing\_exception',  
reason: 'failed to parse the [destinationLongLat] field of type [geo\_point]',  
caused\_by: [Object]},  
operation: {index: [Object]  
'''  
How change the data type of an existing index from geo\_point to text?

You need to reindex, you can't change the mapping once it's been set and used unfortunately.

I would recommend cleaning up the data before indexing it instead as you otherwise will not be able to do any kind of geo analysis.
