> When loading a Python processor, do not load other processor code

> Key: NIFI-13997
> URL: https://issues.apache.org/jira/browse/NIFI-13997
> Project: Apache NiFi
> Issue Type: Improvement
> Reporter: Ferenc Gerlits
> Assignee: Ferenc Gerlits
> Priority: Minor
> Fix For: 2.1.0
>
> Time Spent: 1h 10m
> Remaining Estimate: 0h
>
> When NiFi loads the code for a Python processor contained in a package, it
> loads all Python files in that package (directory). This means that the
> dependencies of all processors in the package must be identical.
> In some cases, the user may want to have the ProcA and ProcB processors in
> the same package to have some common dependencies dep_common (listed in the
> {{requirements.txt}} file) plus each processor to have some extra
> dependencies, say dep_a and dep_b (listed in
> {{ProcessorDetails.dependencies}} in each processor module). When loading
> ProcA, we currently only install the dep_common + dep_a dependencies, but
> then try to load both ProcA and ProcB, which will fail due to the missing
> dep_b dependencies.
> To solve this problem, when we load a processor from a package, we should not
> load any other processors in the same package. We should load all
> non-processor helper files plus the single processor requested by the user.
