Subject [Cassandra Wiki] Update of "Operations" by chrisoei

Dear Wiki user,

You have subscribed to a wiki page or wiki category on "Cassandra Wiki" for change notification.

The "Operations" page has been changed by chrisoei.


  Cassandra is smart enough to transfer data from the nearest source node(s), if your !EndpointSnitch
is configured correctly.  So, the new node doesn't need to be in the same datacenter as the
primary replica for the Range it is bootstrapping into, as long as another replica is in the
datacenter with the new one.
- Bootstrap progress can be monitored using `nodetool` with the `streams` argument.
+ Bootstrap progress can be monitored using `nodetool` with the `netstats` argument (0.7 and
later) or `streams` (Cassandra 0.6).
  During bootstrap `nodetool` may report that the new node is not receiving nor sending any
streams, this is because the sending node will copy out locally the data they will send to
the receiving one, which can be seen in the sending node through the the "AntiCompacting...
AntiCompacted" log messages.
