[jira] [Created] (IMPALA-9721) Fix python 3 compatibility regression

David Knupp created IMPALA-9721:
-----------------------------------

             Summary: Fix python 3 compatibility regression
                 Key: IMPALA-9721
                 URL: https://issues.apache.org/jira/browse/IMPALA-9721
             Project: IMPALA
          Issue Type: Bug
          Components: Clients
            Reporter: David Knupp
            Assignee: David Knupp


The fix for IMPALA-9398 introduced a small regression with regard to python 3 compatibility. We don't have python 3 tests yet to catch regression of this this type, and it was missed in code review.

The regression happens in two places. An example is:
https://github.com/apache/impala/blob/master/shell/impala_shell.py#L248

The syntax for catching exceptions has changed in python 3 to require the "as" keyword.
{noformat}
try:
  do_stuff()
except <exception> as e:
  panic()
{noformat}
