--------------------------------------
Summary: Fix use of deprecated functions / packages in Python3
(long, maxint, file, etc)
Key: IMPALA-11976
URL: https://issues.apache.org/jira/browse/IMPALA-11976
Project: IMPALA
Issue Type: Sub-task
Components: Infrastructure
Affects Versions: Impala 4.3.0
Reporter: Joe McDonnell
Python 3 removed several deprecated functions / types.
{noformat}
# sys.maxint is removed, replace with sys.maxsize
sys.maxint -> sys.maxsize
# file() is removed, use open()
file() -> open()
# Long is gone, int is now equivalent to long, can use int from future
from builtins import int
long() -> int()
# e.message is gone, replace with str(e)
e.message -> str(e){noformat}
There are a grab bag of others like strings.letters becoming
string.ascii_letters and codecs moving to a different package.
This is also a good time to get the new behavior for round().
See these descriptions:

[https://python-future.org/compatible_idioms.html#long-integers]
This corresponds to these pylint checks:
file-builtin
long-builtin
invalid-str-codec

deprecated-string-function
sys-max-int
