I found many queries regarding this measure. Even through, there are queries with respect to this measure and errors, i couldn't find a solution.

I have created a single house and provided illumination map and daylight sensors. However, the radiance measure is not running and creating an error as below:

The missing files are because the Radiance translation did not complete because the OpenStudio model is not set up properly. See my answer below for more info.

Did you connect the illuminance map and daylighting control to a thermal zone? I realize the "error message" here is not terribly informative, but the most likely cause for it is that the translation of the OpenStudio model to Radiance format failed, because the daylighting elements in the model were not fully set up.
