> Key: HDFS-6898
> URL: https://issues.apache.org/jira/browse/HDFS-6898
> Project: Hadoop HDFS
> Issue Type: Bug
> Components: datanode
> Affects Versions: 2.5.0
> Reporter: Gopal V
> Assignee: Arpit Agarwal
> Attachments: HDFS-6898.01.patch, HDFS-6898.03.patch,
> HDFS-6898.04.patch, HDFS-6898.05.patch, HDFS-6898.06.patch, HDFS-6898.07.patch
>
>
> DN will successfully create two RBW blocks on the same volume even if the
> free space is sufficient for just one full block.
> One or both block writers may subsequently get a DiskOutOfSpace exception.
> This can be avoided by allocating space up front.
