Description

In ambari 2.7.5, there are many script still using "python2/python2.6" as the default python version to execute python scripts.

for Ex:

     ambari-server/src/main/resources/common-services/AMBARI_METRICS/0.1.0/package/scripts/params.py: 162:

           ams_monitor_dir = "/usr/lib/python2.6/site-packages"......

 

So In order to adapt change for python3, I would like to make some script modification:

1. change "/usr/lib/python2.6" to "/usr/lib/python3.9"
2. change "/usr/bin/python2" to "/usr/bin/python3"

This modification brings about 70 modification points， but I worry about the compatibility problem, since not all these file can retrieve env veariable to get the actual python version(for Ex: the JSON file).
