Section 5.36. Home Directories in Hdfs

  • In HDFS, home directories are a way of providing a user-specific namespace for storing data. Each user in HDFS has a personal home directory, which acts as a container for the user’s data. This allows each user to have a separate space for storing their data, which can be managed and protected separately from the data of other users.
  • The home directory for a user is typically located in the HDFS root directory under a path similar to /user/<username>. For example, if a user named “jane” logs into HDFS, their home directory would be located at /user/jane.
  • Home directories in HDFS are created automatically when a user first logs into the system. The user has read, write, and execute permissions for their home directory and can use it as they see fit. The administrator of the HDFS cluster can control access to home directories by setting appropriate permissions and ownership.
  • By default, home directories are stored on the HDFS file system, so they can take advantage of HDFS’s built-in features such as data replication, fault tolerance, and scalability. This makes HDFS home directories a convenient and reliable place to store data for individual users or groups of users in a multi-user environment.
