accessing EMR zeppelin api via ssl https

in case of having Shiro authentication for Zeppelin, first you need to login from the command line using the credentials. Please find the below procedure in order to run a job from command line.

The first step is to authentic through the API with a POST to /api/login. I have used the default username and password from shiro.ini file. Use the below command in order to login from command line. Modify the IP address and credentials. In your case it looks something like this. ‘userName=GalGadot&password=WonderWoman’.

curl -i –data ‘userName=admin&password=password1’ -X POST http://ec2-34-27-130-194.us-west-2.compute.amazonaws.com:8890/api/login

The command will return the below output if the login is successful.

HTTP/1.1 200 OK

  1. Next, Using this cookie we can make authorized request to the API by simply setting this as a cookie in the cURL request. Use the “Set-Cookie” from the above output. I got two “Set-Cookie” from my outout. When I gave the first one it failed. However when I tried giving the second one i.e Set-Cookie: JSESSIONID=7143ce79-17be-4900-bad1-5d865bffe000; Path=/; HttpOnly, it worked. So please try the below command with the appropriate cookie. and the job url.  

curl -i -b ‘JSESSIONID=7143ce79-17be-4900-bad1-5d865bffe000; Path=/; HttpOnly’ http://ec2-xx-xx-xxx.us-west-2.compute.amazonaws.com:8890/api/notebook/job/2A94M5J1Z

 

So if the authentication  is successful, it returns the ” 200 OK” http status.

By running the job using the above command, if it is successful, the status will be “FINISHED”. I hope the above information is useful.
