---------------------------------
Summary: Enhance Mpack to handle single-node and small-cluster
installs of Elasticsearch
Key: METRON-609
URL: https://issues.apache.org/jira/browse/METRON-609
Project: Metron
Issue Type: Improvement
Reporter: Matt Foley
Assignee: Matt Foley
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.
* 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.
* 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.
