Hi there!

Currently working on a 4 node cluster just to test out the new MapR v2.0.1.
I haven't had any issues during the installation portion but nothing seems to be working the way it should be, i can't even bring up the Web UI... CLDB is inactive but Zookeeper is running.
/etc/init.d/mapr-cldb status

/opt/mapr/logs/ exists with pid 12280 but no CLDB.

/etc/init.d/mapr-zookeeper status

JMX enabled by default
Using config: /opt/mapr/zookeeper/zookeeper-3.3.2/conf/zoo.cfg
zookeeper running as process 2000.


Here are logs from various errors:
