For me, Hue version 3 was not working. So I switched to version 4. Under cloudera link at the top right, I clicked check configuration. Step 1 was taking a lot of time to check configuration. I clicked on step 2,the examples were displayed, ready to be downloaded. I then went back to step 1 and it had finished checking my configuration, though it had an error. Anyway, I am glad am eventually able to access the examples.
