IMPALA-8337: Fix OrderedDict Python compatibility issue in Impala shell
IMPALA-8317 added a patch that uses OrderedDict, which is not available
on Python 2.6 or lower. The patch in IMPALA-8317 also requires a newer
version of configparser to handle duplicate keys, which is not available
in Python 2.6. This patch fixes the issue by using the OrderedDict from
ordereddict third-party library when running on Python 2.6 or lower and
using configparser from the backport.
Testing:
- Ran all E2E shell tests on Python 2.6 and 2.7
