My Production environment has existing 4 data nodes.
I just added additional 4 data nodes in the cluster and would like to run the HDFS Rebalance to balance the data across the 8 data nodes.
My question is, can I rebalance data but also ingesting and processing new data at the same time? Will it caused any file interrupted if do so?

Hello @newtocm. Yes, You can run your jobs of ingesting and processing data when running the HDFS balancer. But it is ideally recommended to run the balancer when the load on the cluster is not at its peak, so the performance of the jobs are not impacted as balancer is a resource consuming process.
