Tyler Hobbs commented on CASSANDRA-12192:
-----------------------------------------
It looks like the truncate _does_ happen successfully on all nodes, but the
response from the upgraded node to the old node doesn't get through. This
appears to be caused by this schema change:
{noformat}
if is_upgraded:
if self.get_node_version(is_upgraded) >= '3.0':
cursor.execute("CREATE INDEX ON test(m)")
else:
assert_invalid(cursor, "CREATE INDEX on test(m)")
{noformat}
When that schema change is removed, all of the truncates complete successfully.
I'm guessing what happens is that the schema change in a mixed-version cluster
puts the old node in a state where it doesn't correctly handle the truncate
message from the upgraded node. I'll look into this more, but it does seem
like this is a case where we should adjust the test to not perform an
unsupported operation (schema change in a mixed cluster) and expect everything
to work correctly afterwards.
