TPC-DS shows bad performance on Arm server when data on HDFS

Description

Hi team, I have build gluten(volex) with enable_hdfs=on on Arm server.
Generate data set on HDFS, and run TPC-DS benchmark, both steps are using tools/workload/tpcds included in Gluten repo.
But it show poor performance on Arm server when using Gluten.
I found that Gluten depends on libhdfs3, but it has been not updated for nearly 10 years.
So can I ask whether libhdfs3 downgrade the TPC-DS performance when Gluten running in Arm server and data located on HDFS?

Thanks.

hi @eric-yq , can you share your arm cpu information ? e.g., the cpu model, flag, etc.
