I tried to decomission a datanode because of some hardware failures but during decommission process the host rebooted by itself, so now when i click Hosts(ambari) and see the status, the datanode is decomissioned but when i see HDFS dashboard it shows 1 dead and 1 decomissioning.. how can i change this status and how to confirm the node is decomissioned correctly? Do i need to restart namenode?
I cannot restart ambari-server right away. But i was thinking this is not the issue with ambari, even at hadoop level it is showing decomission is in progress, like when i do hdfs dfsadmin -report
Decommission Status : Decommission in progress
