Summary: Fix broken imports on Python 3 and Python 3 object model
differences
Key: IMPALA-11977
URL: https://issues.apache.org/jira/browse/IMPALA-11977
Project: IMPALA
Issue Type: Sub-task
Components: Infrastructure
Affects Versions: Impala 4.3.0
Reporter: Joe McDonnell
Several libraries moved in Python 3. For example, urllib2, httplib, Queue, and
several others. See:
[https://python-future.org/compatible_idioms.html#urllib-module]
[https://python-future.org/compatible_idioms.html#http-module]
This is also a good time to fix several warnings about object model
differences. __nonzero__ is now __bool__, metaclasses are specified
differently, iterator next() method is deprecated, objects that implement
__eq__ should also implement __hash__, etc.
The pylint checks that could be fixed by this would be:
bad-python3-import
eq-without-hash
metaclass-assignment
next-method-called
nonzero-method
comprehension-escape
exception-escape
