---------------------------------------
Summary: Rework setup&configuration of PythonPlanBinder/operators
Key: FLINK-6229
URL: https://issues.apache.org/jira/browse/FLINK-6229
Project: Flink
Issue Type: Improvement
Components: Python API
Affects Versions: 1.3.0
Reporter: Chesnay Schepler
Assignee: Chesnay Schepler
Priority: Minor
Fix For: 1.3.0
The Python API has a few problems in regards to the setup and configuration.
The PythonPlanBinder has several non-final static fields that store critical
information; which python version to use, the path for the distributed cache,
etc. that are directly accessed by operators instead of passing them on
explicitly or storing them in a configuration.
The naming of methods & arguments in the file setup phase (copy to local tmp
location, upload to DFS, register at DC) is less readable than it could be.
The binary path configuration can be stream-lined to use a single key instead
of one each for python2 and python 3.
