Hadoop HDFS File Permissions

Explore reasons why not all users should have free reign over all data sets when managing a data warehouse. In this 9-video Skillsoft Aspire course learners explore how file permissions can be viewed and configured in HDFS (Hadoop File Management System) and how the NameNode UI is used to monitor and explore HDFS. For this course you need a good understanding of Hadoop and HDFS along with familiarity with the HDFS shells and confidence in working with and manipulating files on HDFS and exploring it from the command line. The course focuses on different ways to view permissions which are linked to files and directories and how these can be modified. Learners explore automating many tasks involving HDFS by simply scripting them and to use HDFS NameNode UI to monitor the distributed file system and explore its contents. Review distributed computing and big data. The closing exercise involves writing a command to be used on the HDFS dfs shell to count the number of files within a directory on HDFS and to perform related tasks.
