> Key: HDFS-11295
> URL: https://issues.apache.org/jira/browse/HDFS-11295
> Project: Hadoop HDFS
> Issue Type: Improvement
> Components: namenode
> Affects Versions: 2.7.1
> Reporter: Xiao Liang
> Assignee: Elek, Marton
> Attachments: HDFS-11295.001.patch
>
>
> Currently in BlockPlacementPolicyDefault.chooseReplicaToDelete() the logic
> for choosing replica to delete is to pick the node with the least free
> space(node.getRemaining()), if all hearbeats are within the tolerable
> heartbeat interval.
> However, a node may have multiple storages and node.getRemaining() is a sum
> of the remainings of them, if free space of the storage with the block to be
> delete is low, free space of the node could still be high due to other
> storages of the node, finally the storage chosen may not be the storage with
> least free space.
> So using storage.getRemaining() to choose a storage with least free space for
> choosing replica to delete may be a better way to balance storage usage.
