Subject Marking each node down before rolling restart
Date Wed, 29 Sep 2010 21:15:07 GMT
I looked through the documentation but couldn't find anything.  I was
wondering if there is a way to manually mark a node "down" in the cluster
instead of killing the cassandra process and letting the other nodes figure
out the node is no longer up.

The reason I ask is because we are having an issue when we perform rolling
restarts on the cluster.  Basically read requests that come in on other
nodes will block while they are waiting on the node that was just killed to
be marked down.  Before they realize the node is offline they will throw a

If I could mark the node being down ahead of time this timeout period could
be avoided.  Any help is appreciated.
