[jira] [Created] (HDFS-8072) Reserved RBW space is not released if client terminates while writing block

Arpit Agarwal created HDFS-8072:
-----------------------------------

             Summary: Reserved RBW space is not released if client terminates while writing block
                 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


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.
