Hi all, I am trying to set up an accumulo cluster with kerberos support. I initially used password auth, therefore accumulo wasn't configured with a privileged kerberos principal. After I turned on kerberos, root password doesn't work anymore (obviously..)
I then wanted to re-bootstrap my cluster - a complete rebuild is fine, since there isn't any valuable data. I removed /accumulo from HDFS, and re-ran "accumulo init". This time, I got the chance to enter a valid kerberos principal, which is good. Unfortunately, all the tservers stopped working after this. Looking at the log, it looks like the tserver is saying "ERROR: Got message from a service with a mismatched configuration. Please ensure a compatible configuration." Any ideas what is the proper way rebuild a cluster? Thanks. -Simon
