Attila Doroszlai updated HDDS-8041:
-----------------------------------
Issue Type: Improvement (was: Bug)
> Ozone FS Client should fail to connect if wrong hostname/serviceID in URI.
> --------------------------------------------------------------------------
>
> Key: HDDS-8041
> URL: https://issues.apache.org/jira/browse/HDDS-8041
> Project: Apache Ozone
> Issue Type: Improvement
> Reporter: Sadanand Shenoy
> Assignee: Sadanand Shenoy
> Priority: Major
> Labels: pull-request-available
>
> On providing an incorrect hostname/service ID in ofs URI , the filesystem
> client instead of failing , retries till exhaustion. Also the default retry
> config for client retries is too high currently (500). Considering linear
> retry policy , it would take the client ((1 + 500) * 500 * 2)/2 = 250500
> seconds ~= 70 hours to stop retrying.
