Eric Yang commented on HADOOP-15610:
------------------------------------
[~aw] Hadoop has very little python code. (3 files to be exact). The delta
between Pylint 1.5 and 1.9 are the following new features:
- generated-members
- redefining-builtins-modules
- unsupported-assignment-operation
- unsupported-delete-operation
- tailing-newlines
- useless-super-delegations
- used-prior-global-declaration in Python 3.6 syntax
- python 3 eq-without-hash
- lots of python 3 checks
I don't think any of the existing python code requires any of the new features.
Tailing-newlines is probably the only feature that may be encountered during
the check, if the python files are modified in Hadoop source code. I think
this is still safer than using a pylint that fails encoding test, and save
quite a bit of time to recompile pylint with fluid dependencies that might
change between purges of docker image cache.
