> Key: HDFS-8072
> URL: https://issues.apache.org/jira/browse/HDFS-8072
> Project: Hadoop HDFS
> Issue Type: Bug
> Components: datanode
> Affects Versions: 2.6.0
> Reporter: Arpit Agarwal
> Assignee: Arpit Agarwal
> Fix For: 2.7.0
>
> Attachments: HDFS-8072.01.patch, HDFS-8072.02.patch
>
>
> The DataNode reserves space for a full block when creating an RBW block
> (introduced in HDFS-6898).
> The reserved space is released incrementally as data is written to disk and
> fully when the block is finalized. However if the client process terminates
> unexpectedly mid-write then the reserved space is not released until the DN
> is restarted.
