Following Getting Started with Kibana.

Setup Kibana

Download kibana tar package file (kibana-4.2.0-linux-x64.tar.gz) and extract to $KIBANA_HOME. Modify $KIBANA_HOME/config/kibana.yml, uncomment elasticsearch.url: "http://localhost:9200" (if elasticsearch server is on localhost). Start server with bin/kibana.

Import Data

Import accounts with curl -XPOST 'localhost:9200/accounts/account/_bulk?pretty' --data-binary @accounts.json instead of curl -XPOST 'localhost:9200/bank/_bulk?pretty' --data-binary @accounts.json.

curl -XPOST 'localhost:9200/accounts/account/_bulk?pretty' --data-binary @accounts.json
head -1 accounts.json
{"index":{"_id":"1"}}

curl -XPOST 'localhost:9200/shakespeare/_bulk?pretty' --data-binary @shakespeare.json
head -1 shakespeare.json
{"index":{"_index":"shakespeare","_type":"act","_id":0}}

So if the index and type is not defined in json file, it should be defined when imported with curl.
