There are multiple ways to copy HDFS files to another server. Here are a few commonly used methods:
Remember to replace "/path/to/" with the actual HDFS path and "/path/on/local/server/" with the actual local file system path.
Keep in mind that these commands assume that you have Hadoop installed and the necessary permissions to access the HDFS cluster.

Additionally, you can also copy files from one HDFS cluster to another using DistCp. DistCp (distributed copy) is a tool used for large inter/intra-cluster copying. It is optimized for Hadoop and can copy data in parallel.
Here's how you can use DistCp to copy files from one HDFS cluster to another:

hadoop distcp hdfs://source-cluster:9000/source-path hdfs://destination-cluster:9000/destination-path |
Make sure to replace source-cluster
, source-path
, destination-cluster
, and destination-path
with your actual cluster details and paths.
Using DistCp is a recommended approach for large-scale copying between HDFS clusters as it provides optimizations for efficient data transfer.
