The following best practice checks fail when Cassandra's PasswordAuthenticator is enabled:
- Search nodes enabled with bad autocommit
- Search nodes enabled with query result cache
- Search nodes with bad filter cache
My values are in compliance with the recommended values; and I have confirmed that the checks indeed pass when I disable authentication in Cassandra. What's weird is that there are 6 checks under the "Solr Advisor" category of the Best Practice Service and only these 3 are failing when authentication is enabled.
Is this a known bug in Opscenter? I'm using v5.0.1 but I've seen this since v5.0.0.
Where can I file bug reports like this? Does Datastax have a public bug tracker?
PS:
I actually feel that this question is more appropriate under ServerFault but I don't have enough reputation in that site to create the tags "datastax" and "datastax-enterprise". Can somebody do so please and move this question?
When Cassandra is using PasswordAuthenticator, then the http routes that opscenter agent uses to determine the solr schema settings also become password protected (however the agent does not try the password properly). This is a bug in the opscenter agent, and can be referenced as OPSC-3605.
Unfortunately Datastax Enterprise does not have a public bug tracker. If you're a DSE customer, probably the best method you can use is to go through DSE support.
