Hello, Seems like I was updating the "hdfs-site.xml" on the datanode I want to decommission instead of the namenode. I added the exclude property in the "hdfs-site.xml" on the namenode, executed the refresh command and it worked without restarting the cluster... it is now decommissioning.
Please ignore my previous email. Thank you.
