> Key: HDDS-3786
> URL: https://issues.apache.org/jira/browse/HDDS-3786
> Project: Hadoop Distributed Data Store
> Issue Type: Improvement
> Components: Ozone Client
> Reporter: Wei-Chiu Chuang
> Priority: Minor
>
> For whatever client side operation, the client typically don't hit the leader
> the first time, and the client emits the following message. This is a minor
> issue but kind of scary for a user new to ozone.
