Summary:
TestBootstrapAfterUpgrade.test_upgrade_with_range_tombstone_eoc_0 upgrade test

Key: CASSANDRA-15021
URL: https://issues.apache.org/jira/browse/CASSANDRA-15021
Project: Cassandra
Issue Type: Bug
Components: Test/dtest
Reporter: Vinay Chella
Assignee: Vinay Chella
While running upgrade tests for 3.11.4 candidate I noticed that
{{upgrade_tests.storage_engine_upgrade_test.TestBootstrapAfterUpgrade.test_upgrade_with_range_tombstone_eoc_0}}
is failing with TypeError.
Example run with error:
{code:java}
self = <upgrade_tests.storage_engine_upgrade_test.TestBootstrapAfterUpgrade
object at 0x7f8db9908240>
@since('3.0', max_version='3.99')

E TypeError: can't concat str to bytes
thrift_test.py:153: TypeError
{code}
This TypeError is from Python3 migration. Python 3's standard string type is
Unicode based, and Python 3 adds a dedicated bytes type, but critically, no
automatic coercion between bytes and unicode strings is provided -
[context|https://www.python.org/dev/peps/pep-0404/#strings-and-bytes]
This change in python3 is leading to "TypeError: can't concat str to bytes"
while appending bytes to string.
