@Paula Morais I got the solution for this. After decommissioning the node, first you need to check /etc/hosts file whether decommissioned host is present or not on Name node host. I am sure, it will be there, try to delete that decommissioned host name and restart Namenodes, later check /etc/hosts file. You need to restart the HDFS and Mapreduce i believe, anyway it will show you on ambari dash board which services need to be restarted. Thank you and let me know it is worked for you or not. It worked for me.

@vpoornalingam We are having a small cluster with 30 nodes, in which 18 are data nodes. We assigned 15GB for ambari-server. we deployed our packages through slider in hadoop cluster as a long running jobs. We are not using any ecosystems. Thank you. For how many days, we need to store the AMS data? Is there any specific calculation for that?
