Load data in Powershell Windows

[Yong_Rhee]

Trying to load Shakespear example data into elasticsearch using Windows powershell and got this auth error. (I downloaded file on my User/Documents folder by the way)
I am connected to Elasticsearch port(9200) and Kibana port(5601) successfully and I have gone far to mapping setup before type on Powershell. (PUT method)
And, I also unzipped Logstash.
I am Windows machine.
Plus, I installed Elasticsearch with .msi file so there is no config.yml file on my Elastic 6.3.0 folder as far as I know
