We are using Hortonworks HDP 2.1 (HDFS 2.4), with replication factor 3. We have recently decommissioned a datanode and that left a lot of under replicated blocks in the cluster. Cluster is now trying to satisfy the replication factor by distributing under replicated blocks among other nodes. How do I stop that process. I am OK with some files being replicated only twice. If I change the replication factor to 2 in that directory, will that process be terminated? What's the impact of making the replication factor to 2 for a directory which has files with 3 copies. Will the cluster start another process to remove the excess copy for each file with 3 copies? Appreciate your help on this ... View more
