Zhuqi Jin updated CASSANDRA-15794:
----------------------------------
Discovered By: User Report
Severity: Normal
Since Version: 3.11.4
Description:
We tried to test upgrading a 3.11.4 C* cluster to 4.x and run into the
following problems.
* We started a single 3.11.4 C* node.
* We ran cassandra-stress like this
{code:java}
./cassandra-stress write n = 30 -rate threads = 10 -node 172.17.0.2 {code}
* We stopped this node, and started a C* node running C* compiled from trunk
(git commit: e394dc0bb32f612a476269010930c617dd1ed3cb)
* New C* failed to start with the following error message
{code:java}

We manually deleted all new version commit logs and it worked. However, it's
not obvious whether manually deleting these commit logs are safe.
* And when we run the "ALTER ... DROP COMPACT STORAGE" command on old version
node as the error message suggested, non-existent columns appeared with null
value.
