METRON-1054 Ambari Mpack Attempts to Kill Topologies That Are Not Runâ¦
The Ambari Metron MPack attempts to kill topologies that are not running.
It also attempts to start topologies that are already running. It reports
these conditions as errors. The MPack should not report errors when attempting
to stop an already stopped topology nor when starting an already started
topology.
### Changes
The Ambari MPack management scripts for the Parsers, Enrichment, and
Indexing were all updated so that they only attempt to start topologies that
are not running and only attempt to stop topologies that are running.
### Testing
This can be tested in the Full Dev environment using the following steps.
#### Indexing
(1) Launch Full Dev and ensure all Metron components are running.
(2) `storm kill indexing`
(3) In Ambari, go to http://node1:8080/#/main/services/METRON/summary and
click Service Actions > Restart All.
(4) This action should complete successfully. It should have stopped, then
started the Parsers and Enrichment, but it should have only started Indexing,
since Indexing was not running.
#### Enrichment
(1) Launch Full Dev and ensure all Metron components are running.
(2) `storm kill enrichment`
(3) In Ambari, go to http://node1:8080/#/main/services/METRON/summary and
click Service Actions > Restart All.
(4) This action should complete successfully. It should have stopped, then
started the Parsers and Indexing, but it should have only started Enrichment,
since Enrichment was not running.
#### Parsers
(1) Launch Full Dev and ensure all Metron components are running.
(2) `storm kill bro`
(3) In Ambari, go to the Hosts page at
http://node1:8080/#/main/hosts/node1/summary.
(4) Find the "Metron Parsers" service and click Start on the adjacent
button.
(4) This action should complete successfully. It should have stopped, then
started Snort. It should have only started Bro, since Bro was not running.
