ES seems to be aliasing the byte type to the short type

Elastic Stack Elasticsearch
4

Isn't ther anyone here who belongs to the core ES team and could answer
this question ?
I thought this was the good place to ask but I'm not sure anymore, maybe I
misread the documentation.

Sounds like a bug. If I had to guess I'd say Elasticsearch is rounding
the type up to support unsigned bytes and not doing the range check but I
haven't looked.

Hi everyone,

If was experimenting on mappings for index size optimization purpose and
I have an issue, it seems a bug to me, I cannot find any documentaion about
it.

When I declare a field of type *byte *ES seems to be considering it as
short, for proof see the error message of the last curl below, it
mentions the short type even though I declared a byte
(MapperParsingException[failed to parse [some_data]]; nested:
JsonParseException[Numeric value (32768) out of range of Java short)

Every has been tested on a freshly untared ES.

# Create the index
curl -XPUT 'http://localhost:9200/some_index?pretty' -d '
{
"mappings": {
"some_type": {
"dynamic": "strict",
"properties": {
"some_data": {
"type": "byte"
}
}
}
}
}
'

# Insert a doc with a value just out of the range of the byte type,
success, wierd
curl -XPUT "http://localhost:9200/some_index/some_type/1?pretty" -d '
{
"some_data": 256
}
'

# Insert a doc with the max value for the short type, success, still
wierd
curl -XPUT "http://localhost:9200/some_index/some_type/1?pretty" -d '
{
"some_data": 32767
}
'

# Insert a doc with a value just out of the range of the short type,
failure, ok I get it, ES sees it as a short...
curl -XPUT "http://localhost:9200/some_index/some_type/1?pretty" -d '
{
"some_data": 32768
}
'

java -version outputs :
java version "1.7.0_07"
Java(TM) SE Runtime Environment (build 1.7.0_07-b10)
Java HotSpot(TM) 64-Bit Server VM (build 23.3-b01, mixed mode)

lsb_release -a outputs :
Distributor ID: Ubuntu
Description: Ubuntu 12.04.5 LTS
Release: 12.04
Codename: precise

uname -r outputs:
3.1.10-1.9-ec2

ES info : ES 1.4.0

Thanks in advance for the help.

Damien
