> Key: CASSANDRA-21216
> URL: https://issues.apache.org/jira/browse/CASSANDRA-21216
> Project: Apache Cassandra
> Issue Type: Bug
> Components: Legacy/Local Write-Read Paths
> Reporter: Isaac Reath
> Priority: Normal
> Fix For: 4.1.x
>
> Attachments: ClassCastException-Read.txt,
> ClassCastException-Writes-1.txt

>
> After a schema modification on a cluster serving reads and writes, we have
> noticed that it is possible to see ClassCastException being thrown when
> comparing clustering keys in a few codepaths (see attached stacktraces).
> The table in question is a very wide table, ~4200 columns and it occurred
> originally on a cluster with 30 nodes running 4.1.3.
> I've been able to reproduce it on a 3 node cluster running 4.1.10 with a
> single data center that is doing ~60 req/sec and frequent concurrent schema
> modifications. It appears to be a race as it doesn't happen on every schema
> change, but will occur at a rate of roughly 1/200 schema changes while the
> read/write workload is ongoing.
