Stefan Miklosovic updated CASSANDRA-20892:
------------------------------------------
Change Category: Operability
Complexity: Low Hanging Fruit
Reviewers: Stefan Miklosovic
Status: Open (was: Triage Needed)
> Don't allow JMX operations for denylist when denylist is disabled
> -----------------------------------------------------------------
>
> Key: CASSANDRA-20892
> URL: https://issues.apache.org/jira/browse/CASSANDRA-20892
> Project: Apache Cassandra
> Issue Type: Improvement
> Components: Observability/JMX
> Reporter: Ling Mao
> Assignee: Ling Mao
> Priority: Normal
> Fix For: 4.1.x, 5.0.x, 5.x
>
> Time Spent: 10m
> Remaining Estimate: 0h
>
> While following the documentation ([2]), I executed the following commands
> {code:java}
> bean org.apache.cassandra.db:type=StorageProxy
> run denylistKey foo buz 3
> true
> run loadPartitionDenylist
> run isKeyDenylisted foo buz 3
> false
> {code}
> but encountered some confusing behavior:
> 1. The function _*isKeyDenylisted*_ always returned false, which was
> unexpected.
> 2. However, I observed from the logs that *_loadPartitionDenylist_* executed
> successfully:
> {code:java}
> Loaded partition denylist cache in 24ms{code}
> 3. Additionally, running the query {*}_SELECT * FROM foo.buz WHERE key=3_{*};
> did not throw an exception as anticipated.
> After further investigation, I discovered that the feature needs to be
> explicitly enabled by setting *_partition_denylist_enabled: true_* in the
> _*cassandra.yaml*_ file. Unfortunately, this requirement is not mentioned in
> the documentation ([1], [2]).
