> EC: Fix bug in choosing targets when racks is not enough.
> ---------------------------------------------------------
>
> Key: HDFS-17227
> URL: https://issues.apache.org/jira/browse/HDFS-17227
> Project: Hadoop HDFS
> Issue Type: Bug
> Reporter: Shuyan Zhang
> Assignee: Shuyan Zhang
> Priority: Major
> Labels: pull-request-available
>
> *Bug description*
> If,
> 1. There is a striped block blockinfo1, which has an excess replica on
> datanodeA.
> 2. blockinfo1 has an internal block that needs to be reconstruction.
> 3. The number of racks is less than the number of internal blocks of
> blockinfo1.
> Then, NN may choose datanodeA to reconstruct the internal block, resulting in
> two internal blocks of blockinfo1 on datanodeA, causing confusion.
> *Root cause and solution*
> When we use `BlockPlacementPolicyRackFaultTolerant` for choosing targets and
> the racks is insufficient, `chooseEvenlyFromRemainingRacks` will be called.
> Currently, `chooseEvenlyFromRemainingRacks` calls `chooseOnce`, `chooseOnce`
> use `newExcludeNodes` as parameter instead of `excludedNodes`. When we choose
> targets for reconstructing internal blocks, 'newExcludeNodes' only includes
> datanodes that contain live replicas, and does not include datanodes that
> have excess replicas. This may result in datanodes with excess replicas are
> chosen.
> I think we do not need to use `newExcludeNodes`, just pass `excludedNodes` to
> `chooseOnce`.
