Are you able to connect to the ZK quorum using the ZK shell?
http://hadoop.apache.org/zookeeper/docs/current/zookeeperAdmin.html#sc_zkMulitServerSetup
specifically try (replace "host" with fry or leela - test both hosts):
java -cp zookeeper-3.2.1.jar:lib/log4j-1.2.15.jar:lib/jline-0.9.94.jar
org.apache.zookeeper.ZooKeeperMain -server host:2181
which should output something like:
Connecting to host:2181
Welcome to ZooKeeper!
WatchedEvent: Server state change. New state: SyncConnected
[zk: localhost:2181(CONNECTED) 0]
The shell should indicate if you are able to connect or not, then try
something like:
ls /
[badd1, fo3, foo::bar, p1, zookeeper, p0, foo:bar]
[zk: localhost:2181(CONNECTED) 1]
and see if that works?

Hey-
So I'm trying to run a HBase 0.20.2 test instance on a 4 node hadoop 0.20.0
cluster. I have a 2-server ZK 3.2.1 quorum and I started putting HBase on the
nodes, but I'm running into a problem: Whenever I try to create a test table or
something I get-
NativeException: org.apache.hadoop.hbase.master.NotAllMetaRegionsOnlineException
Then a huge trace. Now, I think this has to do with my zookeeper instance, but
I'm not entirely sure. In my 2 zk nodes I have the following zoo.cfg:
tickTime=2000
dataDir=/home/hadoop/zookeeper-3.2.1/data
clientPort=2181
initLimit=5
syncLimit=2
server.1=fry:2888:3888
server.2=leela:2888:3888
The way I start zookeeper is by running bin/zkServer start on both, and they
then go through leader election etc. Is there something else I should run?
Thanks a lot. I apologize for being a total n00b. Also, I know zookeeper is a
2n+1 system but I don't know how to run a 1 server quorum without having it run
in standalone mode.
