Let me explain you my environment. There are three servers all of them acting as datanode and first two nodes are assigned as Namenode (Active and Standby). After adding some 10 MB of file in HDFS, I want to test the failover but as I explained above the response is slow around 1m 35Sec. But in case of shutting down standby namenode respond is within 2-4 seconds.

HI all, I have configured cluster server with Active-Standby NameNode. But whenever I turn of my active name node my response time is 1m 35 sec in average is this normal or am I missing some configuration. I am not using yarn only hdfs. Thankyou , In Cluster environment, whenever I turnoff my active-namenode the response from standby-namenode is slow on average of 1m 35 sec. Is this response time fine or it should be less. I haven't used yarn and mapreduce. Hadoop is only used for HDFS with kerberos authentication
