Ambari problems with python2.7

[Shashank Prabhakara <sh...@infoworks.io>]

Hi all,

I have a HDP installation managed by ambari and one of the software I need
use python 2.7 with these python packages - hdfs, avro, dataframe,
python-snappy among others.

When I install python2.7 (compiled from code), pip and these packages,
ambari fails to start/restart components citing missing rpm package in
python.

Anybody here can help with these issues - I want avoid setting up python2.7
for ambari separately since this is only installed on one node.

Do you mean the ambari-agent?  You can force it to run on 2.6 by running
this command:

echo "PYTHON=/usr/bin/python2.6" >> /var/lib/ambari-agent/ambari-env.sh


By default it will pick the newest installed version, but that forces it
to pick the one you want.

Yes, To be clear I want to avoid installing rpm-package(and any other) for
python2.7 for ambari.

I'm guessing ambari does not install python2.7, correct me if i'm wrong.
I want to force ambari to run on python2.6 again.

Are you on CentOS 6?  You'll have to leave Python 2.6 installed as well,
since yum on that version only works with 2.6.  You just install python27
as an alternate and point your other software at the alt-install.
