Subject Re: tserver not able to connect
Date Thu, 22 Nov 2012 19:30:44 GMT
Is this a single node instance or a cluster? If cluster, and using multiple
zookeepers, make sure you have them configured together as a quorum and
have then listed properly in the accumulo-site.xml.

Also, this may be a stupid question, but did you initialize accumulo?

Sent from my phone, pardon the typos and brevity.
