Opush is not able to start after the migration of dsc20 to dsc21.
Error in index populate_io_cache_on_flush
We are aware of this issue, we need to update our cassandra driver to the latest version.
This could impact the communication to our cassandra servers.
Any basic use of opush should allow to validate that there's no obvious regression.
Some use on our internal opush server should allow to be more confident about real world behaviour.
ABORTED: Integrated in opush-master #153
OP-104 update cassandra driver to 2.1.2 to support cassandra 2.1 and wire protocol 3 (matthieu.baechler: 0b7f706fd15b6fbcb624e3955b5f2574b712214b)
