Arun KMPtin updated CASSANDRA-10042:
------------------------------------
Description:
I followed this Link http://docs.datastax.com/en/cassandra/2.0/cassandra/configuration/configVnodesProduction_t.html to enable virtual node in existing Data Center.
Data continuously writing in to cassandra.
As per the above step the i starts to migrate cassandra from initial token to virtual node. But in between i found data unavailability from my hector client.
Unavailability start from procedure 2( When i starts pointing client to new data center) to decommissioning old data center. In between i found data unavailability.
