Cassandra reaper
Hi All,
For reaper do we need both file or only one?
Cassandra.reaper.yaml
Cassandra-reaper-cassandra.yaml
RE: [EXTERNAL] Re: Cassandra reaper
Posted by "Durity, Sean R" <SE...@homedepot.com>.
Wait, isn’t this the Apache Cassandra mailing list? Shouldn’t this be on the pickle users list or something?
(Just kidding, everyone. I think there should be room for reaper and DataStax inquiries here.)

Sure thing Abdul,
That's great to hear! Unfortunately, the JMX authentication needs to be in the config file currently. And even if the JMX authentication was stored within Cassandra, we would still need to store connection details within the yaml and storing the JMX authentication credentials within Cassandra may not be ideal from a security standpoint.
The UI keeps logs of all the previous repairs, to the best of my knowledge. If you want to completely uninstall Reaper, you can perform a DROP KEYSPACE reaper_db; from within cqlsh, but that would remove all schedules as well.
Cheers,
Joaquin

Hello Abdul,
Depending on what you want your backend to be stored on, you'll want to use a different file.
So if you want your Reaper state to be stored within a Cassandra cluster, which I would recommend, use this file as your base file:
https://github.com/thelastpickle/cassandra-reaper/blob/master/src/packaging/resource/cassandra-reaper-cassandra.yaml<https://urldefense.proofpoint.com/v2/url?u=https-3A__github.com_thelastpickle_cassandra-2Dreaper_blob_master_src_packaging_resource_cassandra-2Dreaper-2Dcassandra.yaml&d=DwMFaQ&c=MtgQEAMQGqekjTjiAhkudQ&r=aC_gxC6z_4f9GLlbWiKzHm1vucZTtVYWDDvyLkh8IaQ&m=PEWhz4hxiOaWoMVLpyDu5vEkXvAaFOuEwQo32agHoTY&s=BzysNkz8sW4bppmaQYmtONrtpBJ0AIZykql2dhnve6M&e=>
Make a copy of the yaml and include your system-specific settings. Then symlink it to the following location:
/etc/cassandra-reaper/cassandra-reaper.yaml
For completeness, this file is an example of how to use a Postgres server to store the Reaper state:

The yaml file used by the service is located at /etc/cassandra-reaper/cassandra-reaper.yaml and alternate config templates can be found under /etc/cassandra-reaper/configs.

Adapt the config file to suit your setup and then run `sudo service cassandra-reaper start`.

Hello Abdul,
You'll only want one:
The yaml file used by the service is located at
/etc/cassandra-reaper/cassandra-reaper.yaml and alternate config templates
can be found under /etc/cassandra-reaper/configs. It is recommended to
create a new file with your specific configuration and symlink it as
/etc/cassandra-reaper/cassandra-reaper.yaml to avoid your configuration
from being overwritten during upgrades.
Adapt the config file to suit your setup and then run `sudo service
cassandra-reaper start`.
