"24 15:23:47,613 [tabletserver.TabletServer] FATAL: Got message from a
service with a mismatched configuration. Please ensure a compatible
configuration."
I believe that the master will not allow tservers to join the cluster if
their configuration is different. Check that the conf and lib directories
are the same across the cluster.

Subject: Error BAD_CREDENTIALS when tablet server tries to connect
Hi,
I'm setting up an Accumulo cluster, most of the nodes are up and running
except for two of the Tablet Server nodes. When either tries to connect,
they throw the fallowing error:
24 15:23:47,613 [tabletserver.TabletServer] WARN : Got loadTablet message
from unauthenticatable user: !SYSTEM
24 15:23:47,613 [tabletserver.TabletServer] FATAL: Got message from a
service with a mismatched configuration. Please ensure a compatible
configuration.

The Master Node, meanwhile, reports:

tablet server

stop

I've confirmed that /accumulo/conf/accumulo-site.xml contains the same
password, user, and secret for all the nodes, including the ones that won't
connect.
Any help would be appreciated!
