[HBase] Support embedded ZooKeeper
----------------------------------
Key: WHIRR-177
URL: https://issues.apache.org/jira/browse/WHIRR-177
Project: Whirr
Issue Type: Improvement
Affects Versions: 0.3.0
Reporter: Lars George
Assignee: Lars George
Fix For: 0.3.0
This can be achieved like so:
* Check if there is no "zk" role in the template -> set HBaseManagesZK = true
* Emit a zoo.cfg from the HBase post-configure script next to the hbase-site.xml
* Set the option in hbase-env.sh to indicate that HBase manages ZK:
{code}HBASE_MANAGES_ZK=true{code}
Question is how many nodes run ZK? All slaves? A subset?
