Using the 5.3.0 Virtualbox VM; trying to start the cluster; used to work but no longer, now getting this error message:
Command 'Start' failed for cluster 'Cloudera QuickStart'
Command 'ZkStartPreservingDatastore' failed for service 'zookeeper'
Zookeeper appears to be running:
[cloudera@quickstart ~]$ sudo service zookeeper-server start
JMX enabled by default
Using config: /etc/zookeeper/conf/zoo.cfg
Starting zookeeper ... already running as process 23023.
Not seeing any obvious exceptions in the zookeeper logs.
Then tried starting up hbase and that failed with this error:
Service did not start successfully; not all of the required roles started: Service has only 0 Master roles running instead of minimum required 1.
