Hi,
When i try to index my datas elastic return this error message :
MapperParsingException[Failed to parse [foo.strBar]]; nested:
NumberFormatException[For input string: "6.0,3.0"];
I try to change mapping on the existing type by adding
"foo.strBar":{"type":"string"}, and i have this following error :
MergeMappingException[Merge failed with failures {[mapper [foo.strBar]
of different type, current\_type [double], merged\_type [string]]}]
When i make a GET on my _mapping there's no entry for foo.strBar. I try
to cache_/clear but not better.
Is there a way to force the mapping or change it "hotswap" without
deleting it, like "alter table" for sql?

No. As far as I know.

Thanks! Merci.
Is there a way to set all "type" : "string" to all new fields not
defined in mapping to "string".

You can use the dynamic\_template under the root object mapper.
