Re: SAM Ambari ConnectionException

Hi Beejal, if you're using a local sandbox, have you tried 127.0.0.1 instead of sandbox-hdf.hortonworks.com? Also, my sandbox VM is hosting Ambari on port 8080 so the address becomes http://127.0.0.1:8080.

Re: SAM Ambari ConnectionException

David - Thanks for responding. I tried 127.0.0.1 and it doesn't work. BTW, with HDF Sandbox Ambari opens at port 9080.

If I directly try to access this Ambari URL in a separate browser tab, Ambari responds back with JSON data. So it doesn't look like connectivity issue. Maybe it is some internal application (SAM) issue.

Re: SAM Ambari ConnectionException

It works at port 8080 instead of port 9080. So by changing URL to http://sandbox-hdf.hortonworks.com:8080/api/v1/clusters/Sandbox, I was able to add the Service Pool.
