$ cqlsh No appropriate python interpreter found.
Cause

If you use the SCL solution provided to install python27 on RHEL/CentOS 6.x. Adding the following profile script makes it easier to run cqlsh by always running it in a python27 environment. This doesn't break yum or modify the system python version.
/etc/profile.d/cqlsh.sh
# Run cqlsh with python2.7
if [ -f /usr/bin/scl ]; then
if scl -l | grep -q python27 ; then
alias cqlsh='scl enable python27 -- cqlsh'
