MQTT issue after connecting Eclipse Kura with Micorosoft Azure IoT Hub

I have created a connection to Microsoft Azure Cloud using Eclipse Kura: Following is the screen shot of Kura UI: Screen Shot of Kura

When I run Kura server, it is sending some messages(10-15 in one go) to the IOT Hub. Messages number gets increased every few seconds even when there is no package or bundle deployed on Kura.

There is also one EndOfFileException in the logger. Following is the log being generated in Kura:

Any help is appreciated. Also, as I am new to Kura, it would be great if somebody could suggest me step-by-step tutorials on DataService.

Thanks

There is work in progress that we (the Azure IoT SDK team) have just initiated in collaboration with the Kura dev team to have an Eclipse Kura connector for Azure IoT Hub. You can see this work in progress here: https://github.com/andrew-buckley/kura/tree/AzureIntegration
