Trouble Starting Tablet Server
All,
I running Accumulo on a 2 node Cluster. bin/start-all.sh seems to start
everything correctly, but the Tablet Server never starts. When I try to
run the Accumulo shell, I get the following
2013-08-12 10:54:50,116 [impl.ServerClient] WARN : There are no tablet
servers: check that zookeeper and accumulo are running.
Zookeeper is running, but I don't think Accumulo is running 100%.
Here is my accumulo-site.xml

Ya, 1.4.3 doesn't support 2.0, though it's rumored that cloudera patched
1.4.3 so it would. It's probably not very hard to back-port the small
changes we made to get accumulo to run on 2.0. but it will require code
changes.

Thank you for the response Eric. I ended up resolving my problem by adding
the following to my general.classpaths. http://pastebin.com/Um0zPXdS
I am using Accumulo 1.4.3, but I did see the fixes in 1.5.1 :-)
https://github.com/apache/accumulo/blob/master/conf/examples/512MB/native-standalone/accumulo-site.xml
However, I am still having problems. It seems like the Tablet Server is
still having trouble starting. I have found errors in logs from three
different services
1) master_accumulo-master.localdomain.out http://pastebin.com/eTAuu0NV
2) monitor_accumulo-master.localdomain.out http://pastebin.com/LSwpK2hY
3) tserver_accumulo-slave.localdomain.out http://pastebin.com/ubaJiHKQ
I think the problem is in the tserver on accumulo-slave, and the other
problems are incidental. Any thoughts?

Take a look at the accumulo-site.xml files in conf/examples/... There are
some comments in the classpath setting for Hadoop 2.0, which I believe is
the CDH4 base. There may also be a line to change in the accumulo-env.sh
file.

I think I found the problem. First of all, I am using CDH 4. CDH
complicates the $HADOOP_HOME, so I do not think all of the hadoop jars are
on the classpath. If you see my earlier post, I had to manually add
directories to the classpath in order to get the accumulo-master to init
properly.
I found the following in gc_accumulo-master.localdomain.err
http://pastebin.com/cTPU5UrA
I am going to resolve my classpath problems and get back to you..

Are you seeing start-all.sh say that it's starting a tserver on each node?
If so, check the debug logs for the tservers and see what they're reporting
toward the end.
