Hi ,

Iam trying to delete index from elastic search in Cygwin tool .But getting this error below.

{"error":{"root\_cause":[{"type":"security\_exception","reason":"action [indices:admin/delete] requires authentication","header":{"WWW-Authenticate":"Basic realm="shield" charset="UTF-  
8""}}],"type":"security\_exception","reason":"action [indices:admin/delete] requires authentication","header":{"WWW-Authenticate":"Basic realm="shield" charset="UTF-8""}},"status":4

Can you let me know how to delete index.

It appears your Elasticsearch has security enabled. You will need to provide a username and password. If your Cygwin tool does not allow you to provide those, you will need to use a different tool.
