EMR 7.8.0 livy http api not working

[ashic]

I've got a new emr cluster (version 7.8.0) with spark set up. Spark version is 3.5.4 and livy is 0.8.0. Spark is working correctly. However, I seem to be having issues with livy.

I've ssh-ed to the emr cluster. I've checked that the livy-server service is active (running). When I run:

curl http://127.0.0.1:8998/sessions

the response is:

curl: (1) Received HTTP/0.9 when not allowed

I'd appreciate any help in understanding the issue and pointers on resolving this.

I had the same issue for something else. EMR 7.x needs https (secured).

Further since the certificate was not signed, I had to use curl -k
