Thanks Michael, this is what I was hoping for. I reckon that “intelligent compromise” is what goes into a lot of the best software solutions out there.

Ambari has no concept of this natively, so the Metron community had to come up with an intelligent compromise to work around that limitation. If you look in the $METRON_HOME/config directory you should see a series of flag files that indicate what has/has not been successfully configured. This is a non-standard way to workaround issues, but if you delete 1 or more of those files, Ambari will re-attempt to perform the operation when you restart any services that depend on that particular setup. e.g. here is a list I pulled from a full dev install: metron_elasticsearch_template_installed_flag_file metron_enrichment_hbase_configured metron_enrichment_hbase_coprocessor_configured metron_enrichment_kafka_configured metron_enrichment_maxmind_configured metron_indexing_configured metron_indexing_hbase_configured metron_parsers_configured metron_pcap_configured metron_profiler_configured metron_profiler_hbase_configured metron_rest_hbase_configured metron_zookeeper_configured HDFS setup occurs here https://github.com/apache/metron/blob/master/metron-deployment/packaging/ambari/metron-mpack/src/main/resources/common-services/METRON/CURRENT/package/scripts/indexing_master.py#L76 https://github.com/apache/metron/blob/master/metron-deployment/packaging/ambari/metron-mpack/src/main/resources/common-services/METRON/CURRENT/package/scripts/indexing_commands.py#L183 Best, Mike Miklavcic On Tue, Nov 5, 2019 at 10:44 AM Yerex, Tom <[email protected]> wrote: Good morning, I wanted to share with the group that once the top-level “/apps/metron” folder is created, the rest of the folders seem to eventually reappear on their own after a few app restarts in Ambari. I have spun up a development instance of Metron (Centos7), to compare, so far it seems to be working well. Cheers, Tom.

Would someone be able to pinpoint for me the code that builds the /apps/metron directory and sub-directories so I can fix the state of those folders without a reinstallation? Cheers, Tom.
