I got the below 3 parameter about the run speed of Replication from the cloudera's document: Decommissioning and Recommissioning Hosts(https://www.cloudera.com/documentation/enterprise/5-5-x/topics/cm_mc_decomm_host.html). 1. Replication Work Multiplier Per Iteration 2. Maximum number of replication threads on a DataNode 3. Hard limit on the number of replication threads on a DataNode I want to understand if these 3 parameter changing impact the run speed of common write data in the hdfs? I would be grateful if someone could provide the reply. Thanks.

Thank your reply. Due to I doubted when the run of write would generate the 3 replica in the hdfs filesystem(refer to the below figure), these 3 parameters changing might impact the speed of replica generate of run of write. So according your reply, Do the replica generate of run of write be not impacted by these 3 parameters?
