>             Project: Hadoop Common
>          Issue Type: Bug
>          Components: erasure-coding
>            Reporter: Siyao Meng

> Note: This bug was found in Ozone in HDDS-15341 . But Ozone "borrowed" some 
> EC code from Hadoop Common / HDFS, after some digging, the same bug appears 
> to affect HDFS as well. The code change belongs to Hadoop Common, thus filing 
> this HADOOP JIRA.
> Context: https://issues.apache.org/jira/browse/HDDS-15341
