> EC: Fix calculation errors caused by special index order
> --------------------------------------------------------
>
> Key: HADOOP-19180
> URL: https://issues.apache.org/jira/browse/HADOOP-19180
> Project: Hadoop Common
> Issue Type: Bug
> Reporter: Chenyu Zheng
> Assignee: Chenyu Zheng
> Priority: Critical
> Labels: pull-request-available
>
> I found that if the erasedIndexes distribution is such that the parity index
> is in front of the data index, ec will produce wrong results when decoding.
> In fact, HDFS-15186 has described this problem, but does not fundamentally
> solve it.
> The reason is that the code assumes that erasedIndexes is preceded by the
> data index and followed by parity index. If there is a parity index placed in
> front of the data index, a calculation error will occur.
