Subject Re: Added new nodes to cluster but no streams
Date Fri, 13 Feb 2015 12:12:51 GMT
When adding a new node to the cluster I need to wait for each node to receive all the data
from other nodes in the cluster or just wait a few minutes before I start each node?

I have added new nodes to the existing cluster. In Opscenter I do not see any streams... I
presume that the new nodes get the data from the rest of the cluster via streams. The existing
cluster has TB magnitude, and space used in the new nodes is ~90 GB. I must admit that I have
restarted the new nodes several times after adding them . Does this affect boostrap? AFAIK
the new nodes should start loading a part of all the data in the existing cluster.

If it stays like this for a while, it sounds like your bootstraps have hung. Note that in
general you should add nodes one at a time, especially if you are in a version without the
fix for CASSANDRA-2434, in theory adding multiple nodes "at once" might contribute to their
bootstraps hanging.
Stop cassandra on the joining nodes, wipe/move aside their data directories, and try again
one at a time.
