> If we reach this exception handler in tests/common/impala_test_suite.py:
> {code:java}
> try:
>   cls.hs2_client = cls.create_impala_client(protocol='hs2')
> except Exception, e:
>   # HS2 connection can fail for benign reasons, e.g. running with unsupported auth.
>   LOG.info("HS2 connection setup failed, continuing...: {0}", e) <--------
> {code}
> then it will fail with:
> {noformat}
> Traceback (most recent call last):
>   File "/usr/lib64/python2.7/logging/__init__.py", line 851, in emit
>     msg = self.format(record)
>   File "/usr/lib64/python2.7/logging/__init__.py", line 724, in format
>     return fmt.format(record)
>   File "/usr/lib64/python2.7/logging/__init__.py", line 464, in format
>     record.message = record.getMessage()
>   File "/usr/lib64/python2.7/logging/__init__.py", line 328, in getMessage
>     msg = msg % self.args
> TypeError: not all arguments converted during string formatting{noformat}
> The problem is that the statement uses "\{0}" replacements that work with .format() while LOG.info is using "%" replacements.
> We can fix this by using .format ourselves or changing the message to use "%" codes.
