Rukshan,
Double check when you start the Monitor that you have the MAC's
accumulo-site.xml on the classpath. If you still see the ZooKeeper
exception, please provide a stacktrace and some more information on
what you've changed.

hi,
I run amc as separate application and try to write monitoring app
separately. For that i used the Monitor class with some changes.
I need to run them separately and get the statistics data using
Monitor
class.
Thanks and Regards.

Hi Rukshan,
How did you start the Monitor?
The MiniAccumuloCluster is actually a thin wrapper around
MiniAccumuloClusterImpl (in recent versions). If you cast to
MiniAccumuloClusterImpl, you should be able to use the exec
method
to start the Monitor for you which will do the proper classpath
setup for you.
((MiniAccumuloClusterImpl) mac).exec(Monitor.class);
The authentication failure is commonly due to a security
measure we
have in place to ensure that rogue services cannot start
participating in an Accumulo cluster. The value of
`instance.secret`
in accumulo-site.xml is used to control the ACL in
ZooKeeper used to
write to certain znodes (such as those used for service
discovery).
If you see a NoAuthException, it's likely that the service you
started found the wrong accumulo-site.xml (or didn't find
it at all).

Do you have any idea to fix this.
Note that i am running accumulo as mini cluster.
