Subject Re: [Cassandra] Expanding a Cassandra cluster

Thank you all.

I have two more question.

1) Is there any implication in running nodetool repair immediately after bringing a new node
up (before key migration process is completed) ?

        Will it cause some race conditions ? Or will it result in some part of the space
never be reclaimed ?

2) How can I figure out the status of key migration in Cassandra?

Thank you
Emalayan

In a future version Cassandra should automatically clean up for you:

https://issues.apache.org/jira/browse/CASSANDRA-5051

Right now though you have to run cleanup eventually or the space will never be reclaimed.
