Rather than, what I inferred as, disabling streaming cluster-wide until all nodes have been upgraded. > disallow streaming operations while upgrading > - > > Key: CASSANDRA-10619 > URL: https://issues.apache.org/jira/browse/CASSANDRA-10619 > Project: Cassandra > Issue Type: Improvement >Reporter: Jon Haddad > > Cassandra should prevent users from doing streaming operations in the middle > of a cluster upgrade. -- This message was sent by Atlassian JIRA (v6.3.4#6332)

If all nodes aren't reporting the same version? Also, what about very large clusters that may take weeks (months?) to upgrade. Is it really ideal to disallow any streaming for that length of time? > disallow streaming operations while upgrading > - > > Key: CASSANDRA-10619 > URL: https://issues.apache.org/jira/browse/CASSANDRA-10619 > Project: Cassandra > Issue Type: Improvement >Reporter: Jon Haddad > > Cassandra should prevent users from doing streaming operations in the middle > of a cluster upgrade. -- This message was sent by Atlassian JIRA (v6.3.4#6332)

Currently if you try to stream between major versions it just craps out and bites people hard, so it's not like we're adding some ridiculous restriction to streaming. It doesn't work - so I'd rather prevent users from making a tragic mistake than allow them to keep screwing up. If you had 30 servers per rack x 30 racks, you should be able to upgrade 1 rack at a time. That shouldn't take weeks, maybe a couple days? Running a mixed cluster for any significant length of time is just asking for trouble. > disallow streaming operations while upgrading > - > > Key: CASSANDRA-10619 > URL: https://issues.apache.org/jira/browse/CASSANDRA-10619 > Project: Cassandra > Issue Type: Improvement >Reporter: Jon Haddad > > Cassandra should prevent users from doing streaming operations in the middle > of a cluster upgrade. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
