Using Python <2.7.9 with HDP 2.4

[#1]

Hi All,

The documentation says Python 2.6 is required but then right below it says:

"Python v2.7.9 or later is not supported due to changes in how Python performs certificate validation."

Does that mean you can use Python 2.7.X so long as it's less than 2.7.9?

Thanks,

Yes. Python 2.6 is the minimum requirement.

@vpoornalingam Okay and to confirm, python 2.7.8 is the highest version allowed?

[#4]

can we install python 2.7 or later on current running HDP2.4.2 secure cluster, with out breaking any components?

Okay got the answer:

For CentOS 6 and SLES 11: Hortonworks supporst Python 2.6.* (which is what is installed by default). Hortnworks do not support switching to Python 2.7.* on these OSs.

For all other supported OSs (CentOS 7, Ubuntu 12 + 14, Debian 7): Hortonworks support Python 2.7.* (which is what is installed by default). As of Ambari 2.2, there is no longer an issue with 2.7.9 (therefore, you can use 2.7.*).
