Subject bootstrap & rack aware on Cassandra4.1
Date Fri, 30 Oct 2009 15:26:43 GMT
Hi all, we experienced that writing on a rack aware node we get the
following error:

 

ERROR [pool-1-thread-1] 2009-10-30 15:48:55,467 StorageProxy.java (line
179) error writing key 13345671

We haven't understand how bootstrap works in Cassandra and how to enable
or disable it.

With trunk version everything works properly.

 

Thanks
