Subject Node decomission failed
Date Wed, 06 Jun 2012 12:32:24 GMT

We are testing Cassandra and tried to remove a node from the cluster using
nodetool decomission. The node transferred the data, then "died" for about
20 minutes without responding, then came back to life with a load of
50-100, was in a heavy load during about 1 hour and then returned to normal
load. It seems to have stopped receiving new data but it is still in the

The node we tried to remove is the third one:

It seems it is still part of the cluster. What should we do? decomission

How can we know the current state of the cluster?
