Description

I am following the Accumulo 1.3 manual for basic admin with version 1.3.5rc7 on CentOS release 5.6 in a single node setup:

http://incubator.apache.org/accumulo/user_manual_1.3-incubating/Accumulo_Shell.html#Basic_Administration

On the monitor/status page, there are no "Logger Servers" listed. "Log Events" shows the same error multiple times: "there are no loggers registered in zookeeper"

There are 5 Accumulo processes running: tserver, master, gc, monitor, tracer. logger is not running.
The following ports are not open (netstat -vatn)

• logger.port.client
• trace.port.client

The tserver logs are full of this message: "there are no loggers registered in zookeeper"

this issue doesn't happen in Accumulo 1.4 trunk.

Here are some stacktraces from the logs.

In logger.log:
