I didn't know that this was possible or how you managed to do it, but it's obviously illegal. You could try to delete the alias from a running node in the same cluster, either [in Kibana](https://www.elastic.co/guide/en/elasticsearch/reference/current/indices-delete-alias.html) or with a curl command like this: `curl -XDELETE "http://localhost:9200/denmod_y_3698/_alias/denmod_y_3698?pretty"` If that doesn't work you may have to delete the index. But I would try to delete the alias first. ---

The data node is different. The node which am trying to start is just master and ingest node. In error the index name is mentioned as`[denmod_y_3698/g8fYmCo_QYaJKCdcdXONOQ]` and i could see the folder with name `g8fYmCo_QYaJKCdcdXONOQ` in the path `elasticsearch-5.3.1\data\nodes\0\indices`. is this causing the issue? if i delete that folder,can i start the node successfully? ---

Does it mean that you changed the role of the node? It was a data node and you restarted it as an ingest node? Removing the data dir would probably work if an only if the node is not a data node. You are otherwise at risk of loosing some data. ---
