Jonathan Ellis commented on CASSANDRA-4665:
-------------------------------------------
[~pmcfadin] do you have a list of Ways Users Screwed Themselves for us here?
> Add Sanity Checks for User Modifiable Settings
> ----------------------------------------------
>
> Key: CASSANDRA-4665
> URL: https://issues.apache.org/jira/browse/CASSANDRA-4665
> Project: Cassandra
> Issue Type: Improvement
> Components: Core
> Reporter: Benjamin Coverston
> Priority: Trivial
>
> I've looked at a several environments that have had some problems that may
> have been more easily identified if there was some type of warning or error
> thrown if some of the user modifiable settings had some sanity check
> associated with it.
> In one instance I saw a cluster that was having memory issues. After looking
> at the YAML they had:
> index_interval: 32
> I'm not sure why anyone would set this lower than the default. They didn't
> even know what the setting did. Perhaps if we issued a warning on startup in
> cases like this it could have been resolved more quickly and easily.
