Jacek Lewandowski updated CASSANDRA-15833:
------------------------------------------
Test and Documentation Plan:
The issue can be tested by executing the following steps:
1. Start 2 node cluster of C* 3.0
2. Create a keyspace with RF=2, and a sample table with some regular columns
(say of text type), insert some data into that table with CL=QUORUM or ALL
3. Flush created table on both nodes
4. Upgrade the first node either to 3.11 or 4.0
5. Start CQL, set consistency to QUORUM or ALL and enable tracing
6. Query table for a single row with a single regular column
7. Without patch, the tracing output shows the information about digest
mismatch, which is unrecoverable (you can even do full repair), with the patch,
there is no such issue
Status: Patch Available (was: In Progress)
> Unresolvable false digest mismatch during upgrade due to CASSANDRA-10657

> Key: CASSANDRA-15833
> URL: https://issues.apache.org/jira/browse/CASSANDRA-15833
> Project: Cassandra
> Issue Type: Bug
> Components: Consistency/Repair
> Reporter: Jacek Lewandowski
> Assignee: Jacek Lewandowski
> Priority: Normal
> Fix For: 3.11.x, 4.x
>
> Attachments: CASSANDRA-15833-3.11.patch, CASSANDRA-15833-4.0.patch
>
>
> CASSANDRA-10657 introduced changes in how the ColumnFilter is interpreted.
> This results in digest mismatch when querying incomplete set of columns from
> a table with consistency that requires reaching instances running pre
> CASSANDRA-10657 from nodes that include CASSANDRA-10657 (it was introduced in
> Cassandra 3.4).
> The fix is to bring back the previous behaviour until there are no instances
> running pre CASSANDRA-10657 version.
