In EE tests HS2 returned results with smaller precision than Beeswax for
FLOAT/DOUBLE/TIMESTAMP types. These differences are not inherent to the
HS2 protocol - the results are returned with full precision in Thrift
and lose precision during conversion in client code.
This patch changes to conversion in HS2 to match Beeswax and removes
test section DBAPI_RESULTS that was used to handle the differences:
- float/double: print method is changed from str() to ":.16".format()
- timestamp: impyla's cursor is created with convert_types=False to
avoid conversion to datetime.datetime (which has only
microsec precision)
Note that FLOAT/DOUBLE are still different in impala-shell, this change
only deals with EE tests.
Testing:
- ran the changed tests
