Subject Issue restarting cassandra with a cluster running Cassandra 1.2.x and Cassandra 2.0.x
Date Tue, 03 Mar 2015 18:37:26 GMT
Hi,

we have a 52 Cassandra nodes cluster running Apache Cassandra 1.2.13.
As we are planning to migrate to Cassandra 2.0.10, we decide to do
some tests and we noticed that once a node in the cluster have been
upgraded to Cassandra 2.0.x, restarting a Cassandra 1.2.x will fail.

The tests were done on a 6 nodes cluster running Apache Cassandra
1.2.13 (x5) + Apache Cassandra 2.0.10 (x1) and using java 1.7.0_07.
The cassandra 1.2.x is failing with the following error in output.log :

We did some tests with a very simple schema without ReversedType, but
they failed too.

We did look at CASSANDRA-6695 and CASSANDRA-8462, and we had applied
the corresponding patch, but without success.

Does someone know a way to avoid this issue ?
