> Slow ozone hdfs performance when lots of config files
> -----------------------------------------------------
>
> Key: HDDS-9910
> URL: https://issues.apache.org/jira/browse/HDDS-9910
> Project: Apache Ozone
> Issue Type: Bug
> Reporter: George Jahad
> Assignee: George Jahad
> Priority: Major
> Labels: pull-request-available
> Attachments: sparkRenameFlamegraph.png

>
> The ozone hdfs interface spends a lot of time unnecessarily reading config
> files. On our cluster, (as shown in the flame graph below,) 90% of the time
> of a rename is spent reading config files unnecessarily.
> The fix is just to read them once when the hdfs is created, and reuse them
> there after.
> I'll post the fix soon.
