> The remaining space check in BlockPlacementPolicyDefault is flawed
> ------------------------------------------------------------------
>
> Key: HDFS-8863
> URL: https://issues.apache.org/jira/browse/HDFS-8863
> Project: Hadoop HDFS
> Issue Type: Bug
> Affects Versions: 2.6.0
> Reporter: Kihwal Lee
> Assignee: Kihwal Lee
> Priority: Critical
> Labels: 2.6.1-candidate
> Attachments: HDFS-8863.patch, HDFS-8863.v2.patch, HDFS-8863.v3.patch
>
>
> The block placement policy calls
> {{DatanodeDescriptor#getRemaining(StorageType}}}} to check whether the block
> is going to fit. Since the method is adding up all remaining spaces, namenode
> can allocate a new block on a full node. This causes pipeline construction
> failure and {{abandonBlock}}. If the cluster is nearly full, the client might
> hit this multiple times and the write can fail permanently.
