[jira] [Updated] (CASSANDRA-16508) Running cqlsh against cassandra
3 throws error about beta flag not set
[ https://issues.apache.org/jira/browse/CASSANDRA-16508?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Jeff Widman updated CASSANDRA-16508:
------------------------------------
Description:
I just ran `cqlsh` from `trunk` commit 2aa22ba99dcc1dacb07b7af31b2664e7db839063 against a Cassandra 3.11.10 docker image.
I expected that the newer cqlsh would down-negotiate from the v5 protocol to the older v4 protocol.
Instead, I was surprised to get a server error about a beta protocol being used without `BETA_FLAG` being set. I unfortunately had to reboot my computer, so I lost the traceback but I can easily reproduce if needed.
I think what's happening is that this commit promoted v5 out of beta:
https://github.com/apache/cassandra/commit/c9d6c725dd0b4aa5693eb1c6d2221c28e9e99c6e#diff-9e4fe0cfd28004625a8006be8a0bdeab8cbdfb039449fb9501b15e8952577aaaL479
And then when it tries to contact the older cassandra version, it complains that the v5 protocol is now being used without this beta flag being set.
However, I was expecting that cqlsh would catch the error and down-negotiate to v4. Instead, it simply returns the error. Among other things, this prevents cqlsh from being used against mixed-version clusters during a cluster upgrade.
