How to disconnect a data center with Astyanax

["Lu, Boying" <Bo...@emc.com>]

Hi, All,

I need to remove a Cassandra data center from a set of connected Cassandra data centers (I use Cassandra 2.0.7).
I found a related document at http://www.datastax.com/documentation/cassandra/2.0/cassandra/operations/ops_decomission_dc_t.html
But I need to do these in my Java programs.

My understanding is that the step #3 is to change the keyspace definition on all remaining data centers. E.g. I have three data centers connected dc1, dc2 and dc3,
And now I need to disconnect dc3 from them.  After executing step #1 and #2, I need to run step #3 on dc1 and dc2.

Can anyone tell me how to do this with Astyanax APIs?  Can I use KeyspaceDefinition.setStrageOptions() to do this?

Thanks
