@Piyali Gupta Here are the steps to increase HDFS Balancer network bandwidth for faster balancing of data between nodes Article hdfs dfsadmin -setBalancerBandwidth 100000000 on all the DN and the client we ran the command below hdfs balancer -Dfs.defaultFS=hdfs://<NN_HOSTNAME>:8020 -Ddfs.balancer.movedWinWidth=5400000 -Ddfs.balancer.moverThreads=1000 -Ddfs.balancer.dispatcherThreads=200 -Ddfs.datanode.balance.max.concurrent.moves=5 -Ddfs.balance.bandwidthPerSec=100000000 -Ddfs.balancer.max-size-to-move=10737418240 -threshold 5 This will faster balance your HDFS data between datanodes and do this when the cluster is not heavily used.
