METRON-1310 "Template Delete" Action Deletes Search Indices
The "Elasticsearch Template Delete" action within the Indexing service in
Ambari, actually deletes the search indices. Per the name of the action, I
would expect it to only delete the template definitions. This can be quite a
fun surprise. :)
## Testing
1. Spin up Full Dev or an equivalent Metron environment.
1. Query Elasticsearch for the currently defined indices. Take note of all
the indices that you have defined.
```
curl http://node1:9200/_cat/indices?v
```
1. Query Elasticsearch for the currently defined templates. There should
be 5 in all; `snort_index`, `bro_index`, `metaalert_index`, `error_index`, and
`yaf_index`.
```
curl http://node1:9200/_template | python -mjson.tool
```
1. Open Ambari and go to Metron > Metron Indexing. Then on the hosts page,
click on Metron Indexing > Elasticsearch Template Delete.
1. Query Elasticsearch again for the currently defined indices. Make sure
none were deleted.
1. Query Elasticsearch again for the currently defined templates. There
should be none.
```
curl http://node1:9200/_template | python -mjson.tool
```
1. Open Ambari and go to Metron > Metron Indexing. Then on the hosts page,
click on Metron Indexing > Elasticsearch Template Install.
1. Query Elasticsearch again for the currently defined templates. There
should be at least 5 in all.
```
curl http://node1:9200/_template | python -mjson.tool
```
