Hi Su, If you are hitting the same problem, please try hitting the following URL when you see the error in the same browser as Ambari Web:
http://ambari-server:8080/api/v1/hosts?fields=Hosts/last_agent_env For all hosts, you should see JSON like the following: "Hosts" : { "last_agent_env" : { "paths" : [ { "name" : "/etc/hadoop", "type" : "not_exist" }, { "name" : "/etc/hadoop/conf", "type" : "not_exist" }, { "name" : "/etc/hbase", "type" : "not_exist" }, { "name" : "/etc/hcatalog", "type" : "not_exist" }, { "name" : "/etc/hive", "type" : "not_exist" }, { "name" : "/etc/oozie", "type" : "not_exist" }, { "name" : "/etc/sqoop", "type" : "not_exist" }, { "name" : "/etc/ganglia", "type" : "not_exist" }, { "name" : "/etc/nagios", "type" : "not_exist" }, { "name" : "/var/run/hadoop", "type" : "not_exist" }, { "name" : "/var/run/zookeeper", "type" : "not_exist" }, { "name" : "/var/run/hbase", "type" : "not_exist" }, { "name" : "/var/run/templeton", "type" : "not_exist" }, { "name" : "/var/run/oozie", "type" : "not_exist" }, { "name" : "/var/log/hadoop", "type" : "not_exist" }, { "name" : "/var/log/zookeeper", "type" : "not_exist" }, { "name" : "/var/log/hbase", "type" : "not_exist" }, { "name" : "/var/run/templeton", "type" : "not_exist" }, { "name" : "/var/log/hive", "type" : "not_exist" }, { "name" : "/var/log/nagios", "type" : "not_exist" } ], "javaProcs" : [ ], "rpms" : [ { "name" : "nagios", "installed" : false }, { "name" : "ganglia", "installed" : false }, { "name" : "hadoop", "installed" : false }, { "name" : "hbase", "installed" : false }, { "name" : "oozie", "installed" : false }, { "name" : "sqoop", "installed" : false }, { "name" : "pig", "installed" : false }, { "name" : "zookeeper", "installed" : false }, { "name" : "hive", "installed" : false }, { "name" : "libconfuse", "installed" : false }, { "name" : "ambari-log4j", "installed" : false } ], "varRunHadoopPidCount" : 0, "varLogHadoopLogCount" : 0, "etcAlternativesConf" : [ ], "repoInfo" : "Loaded plugins: amazon-id, product-id, rhui-lb, security, subscription-manager\nUpdating certificate-based repositories.\nrepo id repo name status\nHDP-UTILS-1.1.0.15 Hortonworks Data Platform Ut 52\nUpdates-ambari-1.x ambari-1.x - Updates 5\nambari-1.x Ambari 1.x 5\nepel Extra Packages for Enterpris 8,425\nrhui-us-east-1-client-config-server-6 Red Hat Update Infrastructur 2\nrhui-us-east-1-rhel-server-releases Red Hat Enterprise Linux Ser 10,138\nrhui-us-east-1-rhel-server-releases-optional Red Hat Enterprise Linux Ser 5,986\nrepolist: 24,613\n" }, "host_name" : "ip-10-76-191-181.ec2.internal" } If you don't see that for all hosts, your ambari-agent is not the correct version. You should also see the similar output in /var/log/ambari-agent/ambari-agent.log on all of your hosts.
