Bharat Viswanadham created HDDS-5058:
----------------------------------------
Summary: Make getScmInfo retry for a duration
Key: HDDS-5058
URL: https://issues.apache.org/jira/browse/HDDS-5058
Project: Apache Ozone
Issue Type: Bug
Reporter: Bharat Viswanadham
Assignee: Bharat Viswanadham
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, we have seen this issue, after 15 retries Om init
failed, as SCM is started later.
