@James Lee To remove the host from the cluster follow below steps - 1. Stop the ambari-agent on the node. you want to remove. 2. Remove the ambari-agent packages from that node using $yum remove ambari-agent 3. On safer side you can run $hdfs dfsadmin -refreshNamenodes command to refresh nodes on cluster 4. Confirm using $hdfs dfsadmin -report the host is no more part of cluster.

From below screenshot we see that the "-t" is not more with current version of hadoop. You can try - hdfs dfs -ls -R / | sort -k6,7 Check - http://mail-archives.apache.org/mod_mbox/hadoop-hdfs-user/201108.mbox/%3CCAFDdpB10sHYdaJC4JRcHHrcrdiOj4LBU2OZboabh2H3L3UjbEw@mail.gmail.com%3E

@sankar rao You need to check the Resource Manager UI scheduler page http://RM_UI:8088/cluster/scheduler and check for the "Application Queues" usage. Accordingly if you see if few jobs are taking more time[say in Hrs] than they are expected then you might have to kill the jobs and re-run with tuning them. Other option is to make sure you have tune up your MR-Yarn settings to use whole memory of cluster. For tuning refer - https://docs.hortonworks.com/HDPDocuments/HDP2/HDP-2.3.0/bk_installing_manually_book/content/determine-hdp-memory-config.html
