Subject Re: Update default build targets
Date Tue, 06 Jun 2017 14:37:33 GMT
Hmm, I’d rather see our release on versions that are most commonly deployed. A systems with
so many deps as PIO can run afoul of corp version policies. Then a build for all reasonable
deps will take care of edge cases.

py3 and scala 2.11 seem to be the most commonly deployed, not so much for hadoop 2.7 afaict

ES5 I agree is problematic. One big reason to move to it is so users can use SaaS ES, maybe
someone in user land can better say what version is out in SaaS? I’m not concerned with
ES release schedule, at issue is ES adoption level.

Although it might be difficult to define it,
how about the following policy:

- Select newer dependencies
- If the above one is not supported in major platforms(ex. AWS,
 Cloudera, Horton), change to the lower version
- Review the version of dependencies at every releases if needed

As for elasticsearch, I would like to keep a newer version
since it will be released monthly.

Thank you for the info.
CDH seems not to support hadoop 2.7...
Updated as below:


For Python 2/3, I fixed some templates, such as recommender.
Since I think template scripts can support both Python 2/3,
I'll fix them.
