]

Sylvain Lebresne resolved CASSANDRA-8903.
-----------------------------------------
    Resolution: Cannot Reproduce

As said above, it's very unclear from the code of such exception could happen and with no
news on reproduction steps in 1+ month (and no additional report of this), closing as "Cannot
Reproduce".

If you have more information to provide on this that would help reproducing/tracking this
down, feel free to reopen with said information.

> While in the middle of an upgrade of a 12-node cluster, the following errors were constantly
being reported in the logs:
> {noformat}
> ERROR [WRITE-/10.73.73.26] 2015-03-02 22:59:12,523 OutboundTcpConnection.java (line 234)
error writing to /xx.xx.xx.xx 
> java.lang.RuntimeException: Cannot convert filter to old super column format. Update
all nodes to Cassandra 2.0 first.

> at org.apache.cassandra.net.OutboundTcpConnection.run(OutboundTcpConnection.java:151)
> {noformat}
> Confirmed that code is accessing cluster via Thrift and not CQL API.
> This issue is very similar to CASSANDRA-6966 but may relate to the way that single slice
and reversed is being handled.
