Subject [Cassandra Wiki] Update of "FAQ" by gdusbabek
Date Tue, 02 Nov 2010 17:04:30 GMT
Dear Wiki user,

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

The "FAQ" page has been changed by gdusbabek.
The comment on this change is: explained why autoboostrap=false is a bad idea when introducing
empty nodes to a cluster..
http://wiki.apache.org/cassandra/FAQ?action=diff&rev1=92&rev2=93

--------------------------------------------------

  
  In Cassandra 0.5 and above, there is an "AutoBootStrap" option in the config file. When
enabled, using the "-b" options is unnecessary, because new nodes will automatically bootstrap
themselves when they start up for the first time. It is recommended that you leave "InitialToken"
blank for these versions, because the improved bootstrap process will pick a balanced Token
for each node.
  
+ Under no circumstances should you introduce a new empty node to your cluster and have autoboostrap
disabled.  In version 0.7 under write load it will cause writes to be sent to the new node
before the schema arrives from another member of the cluster.  This would also indicate to
clients that the new node is responsible for servicing reads for data that it definitely doesn't
have.
+ 
  In Cassandra 0.4 and below, it is recommended that you manually specify a value for "InitialToken"
in the config file of a new node.
