Accumulo and CDH4 -- "no tablet servers"
Newman, Elise 2013-04-05, 22:46
I am trying to properly configure Accumulo on a cluster running CDH4. I can't seem to get any tablet servers up and running.

I've checked out trunk, built it against cdh4, and ran ./accumulo init.
Then I ran the start-all script, which produced the following output:

./start-all.sh
Starting monitor on localhost
Starting tablet servers ..... done
Starting tablet server on *********
Starting tablet server on *********
2013-04-05 13:04:05,442 [server.Accumulo] INFO : Attempting to talk to zookeeper
2013-04-05 13:04:05,623 [server.Accumulo] INFO : Zookeeper connected and initialized, attemping to talk to HDFS
2013-04-05 13:04:05,766 [server.Accumulo] INFO : Connected to HDFS
Starting master on ********
Starting garbage collector on localhost
Starting tracer on localhost

When I checked http://localhost:50095/tservers, however, it showed that there were no tablet servers online. I looked at http://localhost:50095/log, and saw the following message:

WARN: There are no tablet servers: check that zookeeper and accumulo are running.

I get the same message when I attempt to start the accumulo shell.

In my tracer_master.debug.log I see the following recurring exception:

2013-04-05 15:15:59,742 [impl.ServerClient] DEBUG: ClientService request failed null, retrying ...

Anyone know what could be going on?

Thanks in advance,
Elise
