@Andrey-mp how do we know when this is 100% complete?

[Andrey-mp]

• moved to python3 all components which are not related to cassandra
• switched default from thrift to CQL
• removed pycassa/thrift libraries from build process

next step is to try to switch python definition to python globally and try to build. otherwise - switch it one by one for all components. @qblivion is working on it.

Where are we at?

@qblivion please provide current status.

Greetings Randy @randybias,

Currently, we have two main tasks: updating the analytics package and codebase to Python 3 and migrating the config package to Python 3. Once these tasks are completed, we will be able to drop Python 2 for the entire project.

Right now, I am working on supporting the net-snmp package in the analytics-snmp-collector and refactoring the analytics Python code. I estimate this will take about a week, after which we can finalize the deprecation of Python 2 for the entire project.

Status?

Hello!

I have finished working on the analytics module. It took more time than I anticipated because of the net-snmp package, but it now works correctly with Python 3. I have two parts left: the kubemanager and config packages. The kubemanager is almost done, and I expect the config package to be more challenging. I will keep you updated.

Any ETA?

[Andrey-mp]

I would say - a week since now to switch to python3. and then ensure that python2 is not used - one more week

Updates?

[qblivion]

Ready to merge. All packages should now work on Python 3. We are removing Python 2 dependencies.
