InvalidIndexNameException[[_taste] Invalid index name [_taste], must not start with '_']

[muraree]

@marevol I have installed elasticsearch-taste(0.4.0) with elasticsearch(1.4.2)

I run first three step successfully

1. curl -o u.data http://files.grouplens.org/datasets/movielens/ml-100k/u.data
2. cat u.data | awk '{system("curl -XPOST localhost:9200/movielens/_taste/event?pretty -d "{\"user\":{\"id\":" $1 "},\"item\":{\"id\":" $2 "},\"value\":" $3 ",\"timestamp\":" $4 "000}"")}'
3. curl -XGET "localhost:9200/movielens/search?q=:_&pretty"

But when run forth command to compute recommended items from users:

curl -XPOST localhost:9200/_taste/action/recommended_items_from_user -d '{ "num_of_items": 10, "data_model": { "cache": { "weight": "100m" } }, "index_info": { "index": "movielens" } }'

Getting error: {"error":"InvalidIndexNameException[[_taste] Invalid index name [taste], must not start with '']","status":400}

Could you please let me know if i missing anything Any helps is appreciated. Thanks!

I think plugin installation was failed. Please check elasticsearch's log file.
