Hao Hao commented on SENTRY-957:
--------------------------------
Uploaded the patch for it. Basically:
- Retries the failed task with configurable times. Each retry waits for a
configurable time.
- Client can configure whether to fail the startup (atomic) or continue with
partial paths with log errors available.
> Exceptions in MetastoreCacheInitializer should probably not prevent HMS from
> starting up

> Right now if there is an error condition in evaluating paths in
> MetastoreCacheInitializer in one of the tasks, we throw a Runtime Exception.
> The more I think about, it looks like it would be best to log an error and
> continue; as a plugin should not cause the service to come down? On the other
> hand, doing so might result in incomplete sync which might make it hard to
> get to the root cause.
