Hi, I am running Apache Hadoop Cluster 2.4.1, I have two questions about Hadoop HTML link http://test_namenode:8088/cluster/cluster,
1) If I click "Server metrics” to the page of http://test_namenode::8088/metrics, it is blank. Can anyone please advise if this is normal or I have not yet setup some monitoring tools properly e.g. nagios? 2) On the page http://test_namenode:8088/cluster/cluster, I can see version is "2.4.1 from Unknown" Is there a way to change the word from “Unknown” to a more meaningful word by myself? ResourceManager version: 2.4.1 from Unknown by hadoop source checksum f74…... Hadoop version: 2.4.1 from Unknown by hadoop source checksum bb7…... Many thanks! Regards Arthur
