I see some in the latest commit. It would be nice to remove them.
> Improve Storm config validation process to use java annotations instead of
> *_SCHEMA format
> ------------------------------------------------------------------------------------------
>
> Key: STORM-1084
> URL: https://issues.apache.org/jira/browse/STORM-1084
> Project: Apache Storm
> Issue Type: Improvement
> Components: storm-core
> Reporter: Boyang Jerry Peng
> Assignee: Boyang Jerry Peng
>
> So currently we specify validators:
> public static final String STORM_MESSAGING_NETTY_MIN_SLEEP_MS =
> "storm.messaging.netty.min_wait_ms";
> public static final Object STORM_MESSAGING_NETTY_MIN_SLEEP_MS_SCHEMA =
> ConfigValidation.IntegerValidator;
> A better way to do this is using annotations. Something like:
> @IntegerValidator
> public static final String STORM_MESSAGING_NETTY_MIN_SLEEP_MS =
> "storm.messaging.netty.min_wait_ms";
> Do this has many advantages. For one you can stack multiple annotations:
> @IntegerValidator
> @NotNull
> public static final String STORM_MESSAGING_NETTY_MIN_SLEEP_MS =
> "storm.messaging.netty.min_wait_ms";
> And we don't have to write another validator for strings that cannot be null
> And we can pass parameters into the annotations:
> @PositiveIntegerValidator(notNull=true)
> public static final String DRPC_REQUEST_TIMEOUT_SECS =
> "drpc.request.timeout.secs";
> instead of having to write another validator:
> ConfigValidation.NotNullPosIntegerValidator for checking for not null
