zhouyuan opened a new issue, #5103:
URL: https://github.com/apache/incubator-gluten/issues/5103

   ### Description
   
   Velox hdfs connector is using libhdfs3 which is a C++ based hdfs client.  
The libhdfs3 is from HAWQ project and is not maintained anymore. 
   In Gluten we used the CK libhdfs3 fork, and added the delegation token 
support. (https://github.com/oap-project/libhdfs3)
   However there are still some feature gaps like encrypted 
rpc(https://github.com/ClickHouse/ClickHouse/issues/22236), federated cluster
   
   In practice the HDFS team and Spark team is usually separated so it maybe 
difficult to introduce a new HDFS client.
    Gluten/Velox may also need to support JVM based libhdfs (hadoop default) as 
the second option, so there's no feature gap in HDFS connections.
