----------------------------------
Labels: pull-request-available (was: )
> Automatically create home directory for users
> ---------------------------------------------
>
> Key: HDFS-17926
> URL: https://issues.apache.org/jira/browse/HDFS-17926
> Project: Hadoop HDFS
> Issue Type: Improvement
> Components: namenode
> Reporter: KWON BYUNGCHANG
> Priority: Major
> Labels: pull-request-available
>
> Currently, HDFS does not automatically create a user's home directory (e.g.,
> `/user/<user>`). This requires administrators to manually create home
> directories, which adds operational overhead and can cause failures for
> user-facing tools (e.g., MapReduce job submission, Hive, Spark) that assume
> the home directory exists.
> This JIRA tracks the development of automatic home directory creation so that
> when a user's home directory does not yet exist, HDFS creates it
> automatically with appropriate ownership (`<username>:<supergroup>`) and
> permissions (`drwx------`).
> *Motivation:*
> - Reduces administrative burden for large multi-tenant clusters
> - Prevents job failures caused by missing home directories
> - Aligns with the behavior expected by higher-level ecosystem tools
>
> *Background:*
> This feature was originally developed and added to an internal fork of Apache
> Hadoop 3.1.2, and has been running in production for over a year.
> We plan to port the implementation to 3.5.0 and share the patch here.
