New to elasticsearch, so hopefully the question makes sense... Using
elasticsearch-hadoop (1.3.0.M2-yarn), is it possible to add to a list? I am
currently populating elasticsearch from a m/r job, but it updates the
object as opposed to add an object to the list. I would like to accomplish
something like the following from the update documentation:
We can also add a tag to the list of tags (note, if the tag exists, it will
still add it, since its a list):
curl -XPOST 'localhost:9200/test/type1/1/\_update' -d '{
"script" : "ctx.\_source.tags += tag",
"params" : {
"tag" : "blue"
}
}'
