> The current Mpack for Ambari install of Metron requires that Elasticsearch be installed with 1+ dedicated Masters and 3+ dedicated Slaves. It does not support combined master/datanode configuration (non-"dedicated" Master), which is the recommended way to run a single-node configuration of Elasticsearch; nor does it allow less than 3 dedicated Slaves, thereby requiring the cluster have at least 4 nodes.
> This jira proposes to enable 1-, 2-, and 3-node clusters to have a working Elasticsearch install via the Mpack. It will also allow non-dedicated master/datanodes, which are required for single-node and useful for few-node clusters.
> I intend to also include the following enhancements and fixes:
> * Determine whether elastic-sysconfig:data_dir and elastic-site:path_data should have same default value and if so fix it. (I think they should, and they don't. Probably there should only be one variable instead of two.)
> * Provide Quick Links in Ambari service page for Elasticsearch to the self-report pages for Elasticsearch health, node list, and other "_cat" status. May include some "_cluster" status.
> * Improve various mouse-over Description fields in the GUI
> * Improve the order of fields in the GUI, to group at the beginning the fields that must be modified or are commonly modified. Possibly separate "basic" and "advanced" configs.
> * Provide a README.md that describes what is going on with the various resource files in the Mpack src
> * Enhance the wiki page for cluster installation, with regard to single-node install with Mpack.
> * Database-preserving upgrade from version 1.0.0.0.
> Also see https://github.com/apache/incubator-metron/tree/master/metron-deployment#current-limitations for some other known issues. And the documentation in that README.md page is significantly out of date wrt the Mpack.
