Hi, Does this memory allocation referres to the physical memory allocated to the node? What's the best way to go about resolving this error?   Thanks   cluster : Configuration Issues hadoop5.vm : Memory Overcommit Validation Threshold   Memory on host hadoop5.vm is overcommitted. The total memory allocation is 10.5 GiB bytes but there are only 11.5 GiB bytes of RAM (11.5 GiB bytes of which are reserved for the system). Visit the Resources tab on the Host page for allocation details. Reconfigure the roles on the host to lower the overall memory allocation. Note: Java maximum heap sizes are multiplied by 1.3 to approximate JVM overhead. ... View more

I solved that parcel.torrent time-out problem.  Found out the 4 agent nodes didn't have the hostname of the server in their host file.    Now I just have to take care of those bits and pieces: There are mismatched versions across the system, which will cause failures. See below for details on which hosts are running what versions of components. Cloudera supports versions 1.6.0_31 and 1.7.0_55 of Oracle JVM and later. OpenJDK is not supported, and gcj is known to not work. Check the component version table below to identify hosts with unsupported versions of Java.

Cloudera recommends setting /proc/sys/vm/swappiness to a maximum of 10. Current setting is 60. Use the sysctl command to change this setting at run time and edit/etc/sysctl.conf for this setting to be saved after a reboot. You can continue with installation, but Cloudera Manager might report that your hosts are unhealthy because they are swapping.   ... View more

I recently installed ambari-server on Oracle linux 6.7 within a proxmox VM. I did a custom installation with a mysql local database. All installations completed successfully, but when I enter the ambari install wizard URL "http://10.3.1.45:8080" I get an unable to connect page. I checked the ambari-server log and it shows the following: [root@proxmox-node2 ambari-server]# tail -f 100 ambari-server.log tail: cannot open `100' for reading: No such file or directory ==> ambari-server.log <== 28 Apr 2016 15:12:50,046 INFO [main] Configuration:1084 - Hosts Mapping File null 28 Apr 2016 15:12:50,080 INFO [main] HostsMap:60 - Using hostsmap file null 28 Apr 2016 15:14:13,848 INFO [main] AmbariServer:173 - Found org/apache/ambari/server/controller/AmbariServer.class class in file:/usr/lib/ambari-server/ambari-server-2.2.1.1.70.jar!/org/apache/ambari/server/controller/AmbariServer.class 28 Apr 2016 15:14:14,603 INFO [main] ControllerModule:194 - Detected MYSQL as the database type from the JDBC URL 28 Apr 2016 15:14:17,513 INFO [main] ControllerModule:236 - Using c3p0 ComboPooledDataSource as the EclipsLink DataSource 28 Apr 2016 15:14:20,378 INFO [main] Configuration:754 - Reading password from existing file 28 Apr 2016 15:14:21,913 INFO [main] MLog:80 - MLog clients using log4j logging. 28 Apr 2016 15:14:21,965 INFO [main] Configuration:1084 - Hosts Mapping File null 28 Apr 2016 15:14:21,996 INFO [main] HostsMap:60 - Using hostsmap file null 28 Apr 2016 15:14:48,131 INFO [main] C3P0Registry:204 - Initializing c3p0-0.9.1.1 [built 15-March-2007 01:32:31; debug? true; trace: 10] 28 Apr 2016 15:15:22,650 INFO [main] ControllerModule:194 - Detected MYSQL as the database type from the JDBC URL 28 Apr 2016 15:15:23,660 INFO [main] ControllerModule:236 - Using c3p0 ComboPooledDataSource as the EclipsLink DataSource 28 Apr 2016 15:15:27,789 INFO [main] MLog:80 - MLog clients using log4j logging. 28 Apr 2016 15:15:41,175 INFO [main] C3P0Registry:204 - Initializing c3p0-0.9.1.1 [built 15-March-2007 01:32:31; debug? true; trace: 10] q ^C [root@proxmox-node2 ambari-server]# ambari-server --version 2.2.1.1 Does any know why the apache ambari wizard doesn't load via the ip address of vm node?
