Summary: Enabling Virtural Node causes data shortage from new DC
Key: CASSANDRA-10042

Project: Cassandra
Issue Type: Bug
Components: API, Drivers (now out of tree)
Environment: Linux OS, 2GB RAM, 180 GB Hard Disk
DC1(Old) - 3 Nodes
DC2(New) - 3 Nodes
All machine have same configuration.
Reporter: Arun KMPtin
Fix For: 2.0.x
I followed this 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.
