This fixes it (1) but it is quite ugly. I do not know what is the best course
of action. It would be nice if this in cassandra.spec
{code}
( cd pylib && %{__python} setup.py install --no-compile --root %{buildroot}; )
{code}
would be executed as part of "%post" - after it is installed, %post would use
the right Python version, not the one used upon RPM package build. Then in
"%preun" we would remove it.

> cqlsh on Cassandra 4.1.2 fails on Amazon Linux

> Key: CASSANDRA-18642
> URL: https://issues.apache.org/jira/browse/CASSANDRA-18642
> Project: Cassandra
> Issue Type: Bug
> Components: CQL/Interpreter, Packaging
> Reporter: Stefan Miklosovic
> Assignee: Brandon Williams
> Priority: Normal
> Fix For: 4.0.x, 4.1.x, 5.x
>
> Time Spent: 10m
> Remaining Estimate: 0h
>
> I am on the newest Amazon Linux Version 2023.1.20230629
> When I install cassandra-4.1.2 from Yum repository, it starts fine but cqlsh
> prints this:
> {code}
> [ec2-user@ip-172-31-27-5 ~]$ cqlsh
> Traceback (most recent call last):
> File "/usr/bin/cqlsh.py", line 148, in <module>
> from cqlshlib import cql3handling, pylexotron, sslhandling,
> cqlshhandling, authproviderhandling
> ModuleNotFoundError: No module named 'cqlshlib'
> {code}
> If I change in /usr/bin/cqlsh.py
> {code}
> cqlshlibdir = os.path.join(CASSANDRA_PATH, 'pylib')
> {code}
> to this
> {code}
> cqlshlibdir = os.path.join('/usr/lib/python3.6', 'site-packages')
> {code}
> it works.
> I am not sure if this is the correct way to handle that as not everybody has
> python3.6. There is also no symlink pointing to this. I guess we would need
> to find where packages are for Python we are going to use in cassandra.spec
> and then change cqlsh.py to reflect that?
> {code}
> [ec2-user@ip-172-31-27-5 /]$ sudo find -type d -name site-packages
> ./usr/lib/python3.9/site-packages
> ./usr/lib/python3.6/site-packages
> ./usr/lib64/python3.9/site-packages
> {code}
> I think we need to pass whatever this (1) expands to here (2)
> (1) https://github.com/apache/cassandra/blob/trunk/redhat/cassandra.spec#L167
> (2) https://github.com/apache/cassandra/blob/trunk/bin/cqlsh.py#L78
