Hi , I Create a cluster using Ambari 2.2.2 on centos 7.2. It worked for about four days and I was able to ingest the data using Flume. All of sudden, I am not able to start any service using Ambari. The background operations with progress bar is not appearing and I am seeing the following exception in Ambari server log. 03 Aug 2016 17:15:53,863 ERROR [pool-9-thread-256] BaseProvider:240 - Caught exception getting JMX metrics : Connection refused, skipping same exceptions for next 5 minutes java.net.ConnectException: Connection refused at java.net.PlainSocketImpl.socketConnect(Native Method) at java.net.AbstractPlainSocketImpl.doConnect(AbstractPlainSocketImpl.java:350) at java.net.AbstractPlainSocketImpl.connectToAddress(AbstractPlainSocketImpl.java:206) at java.net.AbstractPlainSocketImpl.connect(AbstractPlainSocketImpl.java:188) at java.net.SocksSocketImpl.connect(SocksSocketImpl.java:392) at java.net.Socket.connect(Socket.java:589) at sun.net.NetworkClient.doConnect(NetworkClient.java:175) at sun.net.www.http.HttpClient.openServer(HttpClient.java:432) at sun.net.www.http.HttpClient.openServer(HttpClient.java:527) at sun.net.www.http.HttpClient.<init>(HttpClient.java:211) at sun.net.www.http.HttpClient.New(HttpClient.java:308) at sun.net.www.http.HttpClient.New(HttpClient.java:326) at sun.net.www.protocol.http.HttpURLConnection.getNewHttpClient(HttpURLConnection.java:1168) at sun.net.www.protocol.http.HttpURLConnection.plainConnect0(HttpURLConnection.java:1104) at sun.net.www.protocol.http.HttpURLConnection.plainConnect(HttpURLConnection.java:998) at sun.net.www.protocol.http.HttpURLConnection.connect(HttpURLConnection.java:932) at sun.net.www.protocol.http.HttpURLConnection.getInputStream0(HttpURLConnection.java:1512) at sun.net.www.protocol.http.HttpURLConnection.getInputStream(HttpURLConnection.java:1440) at java.net.HttpURLConnection.getResponseCode(HttpURLConnection.java:480) at org.apache.ambari.server.controller.internal.URLStreamProvider.processURL(URLStreamProvider.java:209) at org.apache.ambari.server.controller.internal.URLStreamProvider.processURL(URLStreamProvider.java:133) at org.apache.ambari.server.controller.internal.URLStreamProvider.readFrom(URLStreamProvider.java:107) at org.apache.ambari.server.controller.internal.URLStreamProvider.readFrom(URLStreamProvider.java:112) at org.apache.ambari.server.controller.jmx.JMXPropertyProvider.populateResource(JMXPropertyProvider.java:212) at org.apache.ambari.server.controller.metrics.ThreadPoolEnabledPropertyProvider$1.call(ThreadPoolEnabledPropertyProvider.java:180) at org.apache.ambari.server.controller.metrics.ThreadPoolEnabledPropertyProvider$1.call(ThreadPoolEnabledPropertyProvider.java:178) at java.util.concurrent.FutureTask.run(FutureTask.java:266) at java.util.concurrent.Executors$RunnableAdapter.call(Executors.java:511) at java.util.concurrent.FutureTask.run(FutureTask.java:266) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1142) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:617) at java.lang.Thread.run(Thread.java:745) 03 Aug 2016 17:16:09,289 INFO [qtp-ambari-client-445] RequestScheduleR I did the following: a) Removed the content /var/lib/ambari-agent/data and restarted all ambari-agents b) restarted the Ambari-server.
