> Key: HDDS-15093
> URL: https://issues.apache.org/jira/browse/HDDS-15093
> Project: Apache Ozone
> Issue Type: Bug
> Reporter: Wei-Chiu Chuang
> Assignee: Chi-Hsuan Huang
> Priority: Major
>
> EC container placement adopts rack-scatter policy where stripes are placed in
> different racks.
>
> However, the datanode within the same rack is chosen at random. Let's say a
> rack has both 100TB datanode and 400TB datanode, the 100TB datanode will fill
> up sooner than the 400TB datanode. There is no capacity consideration
> implemented intra-rack.
