Subject [jira] Commented: (CASSANDRA-682) After bootstrap, some nodes cannot find keys
Date Fri, 08 Jan 2010 18:53:54 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-682?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12798130#action_12798130

Brandon Williams commented on CASSANDRA-682:
--------------------------------------------

Yes, the tokens are spread evenly and I used 0 instead of 2**127, simply because it's easier
to remember and type.

> I started a 3 node cluster with RF=3 and loaded about 3M keys into it.  I proceeded to
bootstrap a 4th node and it completed.  Upon performing a read test, I found that  two nodes
could find all keys, and two nodes could find none, depending upon which machine I queried.
 Here is the ring output:

> Token 0 was the newly bootstrapped node.  Tokens 127605887595351923798765477786913079296
and 85070591730234615865843651857942052864 were able to read all keys, the other two nodes
were not.
