token_generator_test.TestTokenGenerator test fails on 2.2
Joseph Lynch created CASSANDRA-15012:
----------------------------------------
Summary: token_generator_test.TestTokenGenerator test fails on 2.2
Key: CASSANDRA-15012
URL: https://issues.apache.org/jira/browse/CASSANDRA-15012
Project: Cassandra
Issue Type: Improvement
Components: Test/dtest
Reporter: Joseph Lynch
While running tests for the 2.2.14 candidate I noticed that the {{TestTokenGenerator}} dtests are broken. I reproduced locally as well, the issue appears to be that we're running a python2 script with python3 (since dtests run python3 now).
Should be a quick fix to make the token generator script py2/3 compatible.
Example local run:

will be None. Pass stdout=PIPE and/or stderr=PIPE in order to capture them.
If check is True and the exit code was non-zero, it raises a
CalledProcessError. The CalledProcessError object will have the return code
in the returncode attribute, and output & stderr attributes if those streams
were captured.
If timeout is given, and the process takes too long, a TimeoutExpired
exception will be raised.
There is an optional argument "input", allowing you to
pass a string to the subprocess's stdin. If you use this argument
you may not also use the Popen constructor's "stdin" argument, as
it will be used internally.
The other arguments are the same as for the Popen constructor.
If universal_newlines=True is passed, the "input" argument must be a
string and stdout/stderr in the returned object will be strings rather than
bytes.
