> Reserved RBW space is not released if creation of RBW File fails
> ----------------------------------------------------------------

> Key: HDFS-8626
> URL: https://issues.apache.org/jira/browse/HDFS-8626
> Project: Hadoop HDFS
> Issue Type: Bug
> Reporter: kanaka kumar avvaru
> Assignee: kanaka kumar avvaru
> Priority: Blocker

>
> The DataNode reserves disk space for a full block when creating an RBW block
> and will release the space when the block is finalized (introduced in
> HDFS-6898)
> But if the RBW file creation fails, the reserved space is not released back.
> In a scenario, when the data node disk is full it causes no space left
> {{IOException}}. Eventually even if the disk got cleaned, the reserved space
> is not release until the Data Node is restarted
> Stacktrace for block creation failure is:
> {code} IOException in BlockReceiver constructor. Cause is |
> org.apache.hadoop.hdfs.server.datanode.BlockReceiver.<init>(BlockReceiver.java:264)
> java.io.IOException: No space left on device
> at java.io.UnixFileSystem.createFileExclusively(Native Method)
