Ryan McGuire resolved CASSANDRA-5343.
-------------------------------------
Resolution: Fixed
fair enough, will do the exception handling in the test then.
> 1.2 creates LZ4 compressed users table which is incompatible in mixed 1.2/1.1
> cluster

>
> Key: CASSANDRA-5343
> URL: https://issues.apache.org/jira/browse/CASSANDRA-5343
> Project: Cassandra
> Issue Type: Bug
> Affects Versions: 1.1.9, 1.2.2
> Reporter: Ryan McGuire
>
> * Start with a 3 node 1.1.9 cluster.
> * Take down node1, replace with 1.2.2.
> * Bring node1 back up, the cluster now has mixed versions.
> When node1 comes up, it tries to create a new keyspace: system_auth, which
> looks like this:
> {code}
> CREATE KEYSPACE system_auth WITH replication = {
> 'class': 'SimpleStrategy',
> 'replication_factor': '1'
> };
> USE system_auth;
> CREATE TABLE users (
> name text PRIMARY KEY,
> super boolean
> ) WITH
> bloom_filter_fp_chance=0.010000 AND
> caching='KEYS_ONLY' AND
> comment='' AND
> dclocal_read_repair_chance=0.000000 AND
> gc_grace_seconds=7776000 AND
> read_repair_chance=0.100000 AND
> replicate_on_write='true' AND
> populate_io_cache_on_flush='false' AND
> compaction={'class': 'SizeTieredCompactionStrategy'} AND
> compression={'sstable_compression': 'LZ4Compressor'};
> {code}
> The system_auth.users table is using *LZ4Compressor* which does not work with
> the 1.1.9 nodes. The 1.1.9 nodes return this error in the logs:
> {code}

> It appears that this means that the table creation failed on the 1.1.9 nodes.
> From one of the 1.1.9 nodes:
> {code}
> cqlsh> DESCRIBE KEYSPACE system_auth ;
> CREATE KEYSPACE system_auth WITH replication = {
> 'class': 'SimpleStrategy',
> 'replication_factor': '1'
> };
> USE system_auth;
> CqlTableDef instance has no attribute 'key_aliases'
> {code}
> No mention of the users table.
> I know that schema changes in mixed version 1.1/1.2 clusters are not
> supported, but this table is not one that the user tried to create, it was
> created automatically on startup.
> h2. Steps to reproduce:
> {code}
> ccm create -v 1.1.9 1.1.9
> ccm populate -n 3
> ccm start
> ccm node1 stress
> ccm node1 stop
> {code}
> edit ~/.ccm/1.1.9/cluster.conf and configure cassandra_dir to point to 1.2.2.
> Edit node1's cassandra.yaml to be 1.2 compliant.
> {code}
> ccm node1 start
> {code}
> At this point check node2's log file for the exception.
