resourcemanager

Every time i try to use the Hadoop Resource Manager web interface ( http://resource-manger.host:8088/cluster/ ) i show up logged in as dr.who. My question, how can I login as another user? In this case i want to login as myself and have a higher lever of privileges than dr.who. The user infomation is got from HttpServletRequest#getRemoteUser(). 1. If you deployed an insecure cluster, the simplest way to pass the username to server is by url parameter. For example, http://localhost:8088/cluster?user.name=babu 2. If you deployed a secure cluster, you probably use Kerberos authentication. You can

thanks in advance for any help I am running the following versions: Hadoop 2.2 zookeeper 3.4.5 Hbase 0.96 Hive 0.12 When I go to http://:50070 I am able to correctly see that 2 nodes are running. The problem is when I go to http://:8088 it shows 0 nodes running. I understand that :8088 reflects the resourcemanager and shows the number of nodemanagers running. The daemons all start, but it would appear that the nodemanagers aren't connecting to the resourcemanager. This is the log file: 2013-12-16 20:55:48,648 INFO org.apache.hadoop.yarn.client.RMProxy: Connecting to ResourceManager at /127.0.0

I'm trying to use the ResourceManager in a C# class, but don't know what to substitute for the basename when creating a new instance of the ResourceManager class. I have a separate project that contains the resource files which is referenced by my project above named as the following: Resources.resx Resources.es-ES.resx If I have a code snippet as follows, what should I substitute for the basename when I want to use the English or Spanish version of the resources? ResourceManager RM = new ResourceManager(basename,Assembly.GetExecutingAssembly()); I tried the approach suggested by Tom, but am

I'm trying to write a simple Resource Manager for the little hobby game I'm writing. One of the tasks that this resource manager needs to do is unloading unused resources. I can think of doing this in two ways: When an object no longer requires a reference to the resource, it must call a method of the Resource Manager to signify it is no longer using it; or When an object no longer requires a reference to the resource, it simply sets it to null. Then when the Resource Manager is asked to unload unused resources, it gets the reference count (via reflection?) of each resource. If the reference

No matter how much I tinker with the settings in yarn-site.xml i.e using all of the below options yarn.scheduler.minimum-allocation-vcores yarn.nodemanager.resource.memory-mb yarn.nodemanager.resource.cpu-vcores yarn.scheduler.maximum-allocation-mb yarn.scheduler.maximum-allocation-vcores i just still cannot get my application i.e Spark to utilize all the cores on the cluster. The spark executors seem to be correctly taking up all the available memory, but each executor just keeps taking a single core and no more. Here are the options configured in spark-defaults.conf spark.executor.cores 3

I have two ASP.NET Web projects (ProjectA and ProjectB). When class in ProjectA is instantiating a class of ProjectB which uses a resource file Blah.resx, I get this error: An exception of type 'System.Resources.MissingManifestResourceException' occurred in mscorlib.dll but was not handled in user code. Could not find any resources appropriate for the specified culture or the neutral culture. Make sure "Resources.Blah.resources" was correctly embedded or linked into assembly "App_GlobalResources.sn_flri6" at compile time, or that all the satellite assemblies required are loadable and fully
