can't initialize on hadoop 2.0
I have performed the following steps:

1) Downloaded the just-released Hortonworks 2 sandbox VM (I have also tried
CDH4 VM, and get the same error). Verified HDFS and ZK up and usable.
2) Downloaded the Accumulo 1.5.0 binary tgz and copied the 512 MB example
conf.
3) Modified accumulo-env.sh with
     HADOOP_HOME=/usr/lib/hadoop,
     HADOOP_CONF_DIR=/etc/hadoop/conf,
     ZOOKEEPER_HOME=/usr/lib/zookeeper
4) ./bin/accumulo init

Got the following error:
Thread "init" died null
