Directory Usage Report
The directory usage report allows you to browse the HDFS filesystem in a way that is similar to the HDFS File Browser. However, the Directory Usage Report also allows you to sort the listings and select multiple items and perform actions on them.
You can also view the last access time, the last modified time of any file in a directory, and the total size of all files in the directory. This usage information is updated on an hourly basis.
You can customize the report by adding filters. A number of preconfigured filters are available, and you can create a custom filter.
