> Key: HDDS-5058
> URL: https://issues.apache.org/jira/browse/HDDS-5058
> Project: Apache Ozone
> Issue Type: Bug
> Reporter: Bharat Viswanadham
> Assignee: Bharat Viswanadham

> Fix For: 1.2.0

>
> Previously during init of OM for getScmInfo we used to do RetryForEverWithFixedSleep, but during SCM HA we have removed this.
> This Jira proposes to add a ceration duration to try getScmInfo, instead of retry forever with fixed sleep.
> In a few docker tests CI run, we have seen this issue, after 15 retries Om init failed, as SCM is started later.
> {code:java}
