There may be some unstated environmental dependencies at issue here. If you
run the dtests on an Ubuntu 16.04 LTS environment with the configuration
described in the dtest README.md, then when you run cqlsh by calling the a
ccm Node object's run_cqlsh() function, it will run cqlsh with Python 2.7.
For example, in this kind of environment, I was able to run
cql_tracing_test.py successfully on trunk and cassandra-3.11.
The error you're experiencing is interesting. I did an experiment on an
environment without Python 2.7, and when I tried to run the
cql_tracing_test dtests, I got errors like this instead:
<class 'ccmlib.node.ToolError'>
Subprocess ['cqlsh', 'TRACING ON', None] exited with non-zero status;
exit status: 1;
stderr: No appropriate python interpreter found.
In contrast, the errors you posted look like trying to run the Python 2.7
scripts in a Python 3.x interpreter. Are you testing with a modified
version of cqlsh? Or, do you have a "python2.7" in your path that points to
Python 3.x?
