##Popup while clicking on "upload".

Unable to connect to the
on-premise SmartSense Gateway (host: 770745-hadoopmaster03.abcxyz.com, port:
9451). Please verify the gateway.host and gateway.port properties in the HST
Server configurations are set correctly and the on-premise SmartSense Gateway
is up and running.

Reason:

Gateway had a filter which would reject any requests if the host url started with a number.

Solution:

The pattern matcher for host in the url is fixed in 1.3.1. Upgrade to 1.3.1 or rename the gateway host to remove the preceding numbers and restart the gateway. SmartSense 1.3.1 upgrade documents : http://docs.hortonworks.com/HDPDocuments/SS1/SmartSense-1.3.1/bk_installation/content/upgrade_scenar...
