Vara Kumar commented on CASSANDRA-5793:
---------------------------------------
Should we apply a patch to handle in this way (return hex value if OPP fails to
encode bytes to UTF-8 instead of throwing error) & mark OPP as unsupported in
relevant documentation?
> OPP seems completely unsupported
> --------------------------------
>
> Key: CASSANDRA-5793
> URL: https://issues.apache.org/jira/browse/CASSANDRA-5793
> Project: Cassandra
> Issue Type: Bug
> Components: Core
> Affects Versions: 1.2.5
> Environment: Cassandra on Ubuntu
> Reporter: Vara Kumar
> Fix For: 1.2.9
>
>
> We were using 0.7.6 version. And upgraded to 1.2.5 today. We were using OPP
> (OrderPreservingPartitioner).
> OPP throws error when any node join the cluster. Cluster can not be brought
> up due to this error. After digging little deep, We realized that "peers"
> column family is defined with key as type "inet". Looks like many other
> column families in system keyspace has same issue.
> Exception trace:
> java.lang.RuntimeException: The provided key was not UTF8 encoded.

> Possibilities:
> - Changing partitioner to BOP (or something else) fails while loading
> schema_keyspaces. So, it does not look like an option.
> - One possibility is that getToken of OPP can return hex value if it fails to
> encode bytes to UTF-8 instead of throwing error. By this system tables seem
> to be working fine with OPP.
> - Or Completely remove OPP from code base & configuration files. Mark clearly
> that OPP is no longer supported in upgrade instructions.
