> Key: HDFS-6604
> URL: https://issues.apache.org/jira/browse/HDFS-6604
> Project: Hadoop HDFS
> Issue Type: Bug
> Components: hdfs-client
> Affects Versions: 2.4.0
> Environment: Centos 6.5 and distribution Hortonworks Data Platform
> v2.1
> Reporter: Giuseppe Reina
> Assignee: Colin Patrick McCabe
> Priority: Critical
> Fix For: 2.5.0
>
> Attachments: HDFS-6604.001.patch, HDFS-6604.002.patch
>
>
> When HDFS shortcircuit is enabled, the file descriptors of the deleted HDFS
> blocks are kept open until the cache is full. This prevents the operating
> system to free the space on disk.
