Maulin Vasavada commented on CASSANDRA-20484:
---------------------------------------------
Okay, so few more questions,
# When you use `-f` option to specify cassandra.yaml path, are you
inheriting/copying the same file that you use for the Cassandra service/server?
(i.e. either you are running sstablesloader from one of the server nodes (hence
can access the same file) OR copied the file over to a VM where you are running
sstableloader from)
# If you are NOT using the same file (either by sharing the location or
copying it over) as the server's cassandra.yaml, then you must be creating a
new/separate cassandra.yaml file just to use it for the sstableloader, correct?
## If this is the case, in my opinion what you specify in the
client_encryption_options AND server_encryption_options must be the same config
because to the Cassandra target nodes you connect with (for native transport or
storage port) your VM is a 'client' and whatever server configured for SSL you
need to comply with. This means if the server configured to require_client_auth
you will need to have keystore for providing your client certs AND truststore
to trust server cert. If the server configured required_client_auth as false
you ONLY need a truststore to be able to trust server cert.
Now, coming to you original question/ask - That if your config file used for
the ssltableloader tool (not the config file inherited/copying from the
server's config) specified the `require_client_auth` false you should not
require truststore - does not logically make sense to me. This is because as a
client you don't control if you require the client to auth with server or not
and as a client if you do have to use SSL (since server configured
client_encryption_options as enabled on its side) you MUST need a truststore
always to be able to validate server's cert.
Also, when I think about the sstableloader options from the documentation
standpoint
([link|[https://cassandra.apache.org/doc/4.0/cassandra/tools/sstable/sstableloader.html#usage]])
- From the command line it ONLY has "Client SSL" options overrides and not
server encryption options overrides - why? I think its because no matter how
you see sstableloader communicating to the server (native or streaming way) -
it is still a client to a SSL server.
Overall, either I fail to completely understand the current sstableloader
documentation/code OR the documentation could be better in clearly calling out
(how Google Gemini AI search results tell the story- see the screenshot below)
- specially focus on the #2 it says similar to what I suggest here.
