------------------------------
Summary: Enhance fuse-dfs mounting to support mounting HDFS to
specific subdirectories
Key: HDFS-17712
URL: https://issues.apache.org/jira/browse/HDFS-17712
Project: Hadoop HDFS
Issue Type: Improvement
Components: fuse-dfs
Affects Versions: 3.4.1, 3.3.6
Reporter: sohurdc
Currently, {{fuse-dfs}} only supports mounting HDFS to the root directory
({{{}/{}}}). While this design is simple and convenient, it presents some
challenges and security concerns in multi-tenant environments. The specific
issues are as follows:
# {*}Limited Multi-Tenant Support{*}: In multi-tenant environments, all tenant
data is mounted under the same root directory, which may lead to poor data
isolation and fail to meet data security requirements.
# {*}Inconvenience in Deep Directory Structures{*}: When the HDFS directory
structure is deep, operations become cumbersome. Especially when frequent
access to specific subdirectories is required, the current design of root
directory mounting limits flexibility and convenience.
{*}Suggestion{*}:
Enhance the {{fuse-dfs}} functionality to support mounting HDFS to
user-specified subdirectories, rather than only the root directory. This would:
* Improve multi-tenant management by meeting data isolation needs.
* Enhance operational convenience, especially in scenarios where specific
subdirectories need to be frequently accessed.
I hope to see this enhancement in future releases, and I appreciate the efforts
of the team!
