Hi All,

I see v2.0 document shown update mapping page, but cannot see the page in 1.7.3, is it possible to update index mapping or some other way to do it?

I think I'm having the same issue that I was trying to update to ES2.0, and failed.

I checked with Elasticsearch Migration Checker v0.16 and it was giving me that "Conflicting field mappings".

`Mapping for field 41bcc7oqmev1zaaxocmg:weight conflicts with: vjzm2ddrzlvjfgnpubgg:weight. Check parameter: type Mapping for field 41bcc7oqmev1zaaxocmg:weight conflicts with: vk-e8temmlekgeute7ze:weight. Check parameter: type`

I looked into the problem and figured out that some weight field was in 'long' and some others were as 'double'.

Is there anyway to force cast the types?

Thanks

"Update mapping _page_"—not sure what you're talking about here.

Changing how a field is mapped (e.g. its data type) requires all documents to be reindexed into a new index with adjusted mappings.

Sorry that typing mistake (it should be update field mapping)
