This patch reverses the revert of IMPALA-7660. The problem with IMPALA-7660 was that urllib.urlopen added the 'context' parameter in 2.7.9, so it isn't present on rhel7, which uses 2.7.5 The fix is to switch to using the 'requests' library, which supports ssl connections on all the platforms Impala is supported on. This patch also adds more info to the error message printed by start-impala-cluster.py when the debug webserver cannot be reached yet to help with debugging these issues in the future. Testing: - Ran full builds on rhel7, rhel6, and ubuntu16.
