GitHub user justinleet opened a pull request:

METRON-386 Create Ambari Service Definition for Elasticsearch
https://issues.apache.org/jira/browse/METRON-386
Opening the PR to get community feedback.
Prereq:
Ambari 2.4
Testing this PR:
*Copy or mount the services and stack contents into the appropriate places on the ambari-server node. For example:
** incubator-metron/metron-deployment/packaging/ambari/src/main/resources/stacks/HDP/2.4/services/ELASTICSEARCH -> /var/lib/ambari-server/resources/stacks/HDP/2.4/services/ELASTICSEARCH **incubator-metron/metron-deployment/packaging/ambari/src/main/resources/common-services/ELASTICSEARCH -> /var/lib/ambari-server/resources/common-services/ELASTICSEARCH
* ES Master eligible nodes will not contain data. Don't colocate master eligible nodes and data nodes.
* It's necessary to provide the ES zen_discovery_ping_unicast_hosts.
Limitations / Notes
* This is based off of Symantec's work at: https://github.com/Symantec/ambari-elasticsearch-service. Should I add this into the NOTICE that includes similar contributions?
* Most configs are used from Symantec's build. If there are more sane configs, we should change the defaults (I'm not an ES expert by any means).
* It would be really nice if zen_discovery_ping_unicast_hosts could be automatically populated with something sane. I'm unsure of how to accomplish this with Ambari.
* Master-eligible nodes are non-data holding nodes that are eligible to be elected master. Data nodes are, not surprisingly, nodes that only hold data, but are not master-eligible. It would be nice if thing could be modified to allow master eligible nodes to also hold data cleanly, but this is left as a further enhancement if needed.
* A service advisor definition could probably be added to force Ambari to avoid placing master-eligible and data nodes onto the same node.
