> 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
> Assignee: Joe McDonnell
> Priority: Major
> Fix For: Impala 4.3.0
>
>
> 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
