httpclientutil | HttpClient工具类，简单轻松的实现get，post，put和delete请求 | HTTP Client library

To reuse HttpClient, I created a utility class like this on ASP.Net Core 2.0.

I have a custom Telemetry Processor that sends custom exception fields to Application Insights.

For example if I throw a custom exception like this one

I'm trying to use the fabric8io/kubernetes-client in a simple example on my local minikube cluster where I get an IP of a pod

I'm trying to get a spark kubernetes install working where the spark driver node resides in its own separate pod (client mode), and uses the SparkSession.builder mechanism to bootstrap the cluster (not using spark-submit).

I'm working from this:

https://spark.apache.org/docs/latest/running-on-kubernetes.html

Here is the code used by the driver to bootstrap the cluster:

About to clean up any left over selenium pods created by Zalenium Usage: [options] Options: --debug, -debug : enables LogLevel.FINE. Default: false --version, -version Displays the version and exits. Default: false -browserTimeout in seconds : number of seconds a browser session is allowed to hang while a WebDriver command is running (example: driver.get(url)). If the timeout is reached while a WebDriver command is still processing, the session will quit. Minimum value is 60. An unspecified, zero, or negative value means wait indefinitely. -matcher, -capabilityMatcher class name : a class implementing the CapabilityMatcher interface. Specifies the logic the hub will follow to define whether a request can be assigned to a node. For example, if you want to have the matching process use regular expressions instead of exact match when specifying browser version. ALL nodes of a grid ecosystem would then use the same capabilityMatcher, as defined here. -cleanUpCycle in ms : specifies how often the hub will poll running proxies for timed-out (i.e. hung) threads. Must also specify "timeout" option -custom : comma separated key=value pairs for custom grid extensions. NOT RECOMMENDED -- may be deprecated in a future revision. Example: -custom myParamA=Value1,myParamB=Value2 -host IP or hostname : usually determined automatically. Most commonly useful in exotic network configurations (e.g. network with VPN) Default: 0.0.0.0 -hubConfig filename: a JSON file (following grid2 format), which defines the hub properties -jettyThreads, -jettyMaxThreads : max number of threads for Jetty. An unspecified, zero, or negative value means the Jetty default value (200) will be used. -log filename : the filename to use for logging. If omitted, will log to STDOUT -maxSession max number of tests that can run at the same time on the node, irrespective of the browser used -newSessionWaitTimeout in ms : The time after which a new test waiting for a node to become available will time out. When that happens, the test will throw an exception before attempting to start a browser. An unspecified, zero, or negative value means wait indefinitely. Default: 600000 -port : the port number the server will use. Default: 4445 -prioritizer class name : a class implementing the Prioritizer interface. Specify a custom Prioritizer if you want to sort the order in which new session requests are processed when there is a queue. Default to null ( no priority = FIFO ) -registry class name : a class implementing the GridRegistry interface. Specifies the registry the hub will use. Default: de.zalando.ep.zalenium.registry.ZaleniumRegistry -role options are [hub], [node], or [standalone]. Default: hub -servlet, -servlets : list of extra servlets the grid (hub or node) will make available. Specify multiple on the command line: -servlet tld.company.ServletA -servlet tld.company.ServletB. The servlet must exist in the path: /grid/admin/ServletA /grid/admin/ServletB -timeout, -sessionTimeout in seconds : Specifies the timeout before the server automatically kills a session that hasn't had any activity in the last X seconds. The test slot will then be released for another test to use. This is typically used to take care of client crashes. For grid hub/node roles, cleanUpCycle must also be set. -throwOnCapabilityNotPresent true or false : If true, the hub will reject all test requests if no compatible proxy is currently registered. If set to false, the request will queue until a node supporting the capability is registered with the grid. -withoutServlet, -withoutServlets : list of default (hub or node) servlets to disable. Advanced use cases only. Not all default servlets can be disabled. Specify multiple on the command line: -withoutServlet tld.company.ServletA -withoutServlet tld.company.ServletB org.openqa.grid.common.exception.GridConfigurationException: Error creating class with de.zalando.ep.zalenium.registry.ZaleniumRegistry : null at org.openqa.grid.web.Hub.(Hub.java:97) at org.openqa.grid.selenium.GridLauncherV3$2.launch(GridLauncherV3.java:291) at org.openqa.grid.selenium.GridLauncherV3.launch(GridLauncherV3.java:122) at org.openqa.grid.selenium.GridLauncherV3.main(GridLauncherV3.java:82) Caused by: java.lang.ExceptionInInitializerError at de.zalando.ep.zalenium.registry.ZaleniumRegistry.(ZaleniumRegistry.java:74) at de.zalando.ep.zalenium.registry.ZaleniumRegistry.(ZaleniumRegistry.java:62) at sun.reflect.NativeConstructorAccessorImpl.newInstance0(Native Method) at sun.reflect.NativeConstructorAccessorImpl.newInstance(NativeConstructorAccessorImpl.java:62) at sun.reflect.DelegatingConstructorAccessorImpl.newInstance(DelegatingConstructorAccessorImpl.java:45) at java.lang.reflect.Constructor.newInstance(Constructor.java:423) at java.lang.Class.newInstance(Class.java:442) at org.openqa.grid.web.Hub.(Hub.java:93) ... 3 more Caused by: java.lang.NullPointerException at java.util.TreeMap.putAll(TreeMap.java:313) at io.fabric8.kubernetes.client.dsl.base.BaseOperation.withLabels(BaseOperation.java:411) at io.fabric8.kubernetes.client.dsl.base.BaseOperation.withLabels(BaseOperation.java:48) at de.zalando.ep.zalenium.container.kubernetes.KubernetesContainerClient.deleteSeleniumPods(KubernetesContainerClient.java:393) at de.zalando.ep.zalenium.container.kubernetes.KubernetesContainerClient.initialiseContainerEnvironment(KubernetesContainerClient.java:339) at de.zalando.ep.zalenium.container.ContainerFactory.createKubernetesContainerClient(ContainerFactory.java:38) at de.zalando.ep.zalenium.container.ContainerFactory.getContainerClient(ContainerFactory.java:22) at de.zalando.ep.zalenium.proxy.DockeredSeleniumStarter.(DockeredSeleniumStarter.java:59) ... 11 more ...........................................................................................................................................................................................GridLauncher failed to start after 1 minute, failing... % Total % Received % Xferd Average Speed Time Time Time Current Dload Upload Total Spent Left Speed 100 182 100 182 0 0 36103 0 --:--:-- --:--:-- --:--:-- 45500

If using Kubernetes, specify your environment, and if relevant your manifests: I use the templates as is from https://github.com/zalando/zalenium/tree/master/docs/k8s/helm

I guess it has to do something with rbac because of this part "Error initialising Kubernetes support. io.fabric8.kubernetes.client.KubernetesClientException: Operation: [get] for kind: [Pod] with name: [zalenium-zalenium-hub-6bbd86ff78-m25t2] in namespace: [default] failed. at "

I created a clusterrole and clusterrolebinding for the service account zalenium-zalenium that is automatically created by the Helm chart.
