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.
After rebuild nodes in new data center, all nodes in new data center gains data.
As per the above step i starts to migrate cassandra from initial token to
virtual node. But in between i found data ( Data which added after rebuild) is
unavailable from new data center.
>From new data center unavailability start from rebuild nodes in new data
>center. After decommission nodes in old data center every thing comes normal.
