Installing Hadoop, ZooKeeper, AccumuLo on Mac

Question

I am attempting to install these technologies on a OS X loaded with Mountain Lion for testing purposes. The setup is a single-node setup using 'localhost'.

I am running into a few issues...

1) running sudo zkCli -> ls / throws an error

Exception in thread "main" org.apache.zookeeper.KeeperException$ConnectionLossException: KeeperErrorCode = ConnectionLoss for /
    at org.apache.zookeeper.KeeperException.create(KeeperException.java:99)
    at org.apache.zookeeper.KeeperException.create(KeeperException.java:51)

    at org.apache.zookeeper.ZooKeeperMain.run(ZooKeeperMain.java:323)
    at org.apache.zookeeper.ZooKeeperMain.main(ZooKeeperMain.java:282)

2) I attempt to run bin/accumulo init and receive this error...

Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/accumulo/start/Platform
Caused by: java.lang.ClassNotFoundException: org.apache.accumulo.start.Platform

It seems that there is something wrong with my class but I am not sure what I need to do.

Here is the summary of the AccumuLo compile:

Answer 1

1) Is Zookeeper running?

2) I would recommend running Accumulo from the binary tarball download instead of building it yourself. If you must build it, use mvn package -P assemble. Are you running from trunk? If so, we no longer run accumulo from the source directory. Look for a built tarball in assemble/target, install that and run it. Is accumulo-env.sh configured properly? Do you have any old environment variables configured in your bash scripts setting an incorrect ACCUMULO_HOME?
