问题 I'm trying to configure SASL/PLAIN with SSL in our Kafka environment. The SSL part is done, but I'm running into the below error when starting the Zookeeper. Has anyone configured SASL/PLAIN with SSL for Zookeeper and broker ? Server-Broker Config broker.id=19 port=19001 #host.name=localhost host.name=jcia9081 #advertised.host.name=11.72.29.153 num.network.threads=3 num.io.threads=8 socket.send.buffer.bytes=102400 socket.receive.buffer.bytes=102400 socket.request.max.bytes=104857600 log.dirs=

问题 This is cross posted from the fusesource forum and the servicemmix forum. I can't get DOSGi working in FUSE. I'm trying to get CXF's DOSGi 1.1-SNAPSHOT with Zookeeper discovery onto FUSE 4.1.0.2. I'm also using Zookeepr 3.2.1. Everything works perfectly on Felix 2.0.0. I just follow the instructions on the DOSGi Discovery page and then install the Discovery Demo bundles. For DOSGi, I just use the cxf-dosgi-ri-singlebundle-distribution-1.1-SNAPSHOT.jar for DSW and cxf-dosgi-ri-discovery

问题 In Heron, I instantiated a SchedulerStateManagerAdaptor named adaptor using IStateManager and created a new Runtime config to saved this adaptor. Then, I created a ISchedulerClient object for invoking its schedulerClient.updateTopology function. Code as follows: String stateMgrClass = Context.stateManagerClass(this.config); // get state manager instance IStateManager stateMgr = null; try { stateMgr = ReflectionUtils.newInstance(stateMgrClass); FileUtils.writeToFile(filename, "Create

问题 I have 3 nodes where Kafka is installed. All these 3 nodes have their own zookeeper instances. Are 3 zookeeper instances required or is 1 zookeeper instance suffice? Should we have multiple zookeeper instances for fault tolerance & in such a scenario would one of the instances act as primary and would others be replica? 回答1: I'm not sure what you mean by "All these 3 nodes have their own zookeeper instances" Basically you should have a single cluster of one, three or five Zookeeper instances

问题 I would appreciate guidance on accumulo, zookeeper hadoop Installation instructions, downloads and versions for CENTOS 6. Thanks, Chris 回答1: You can do the installation via cloudera manager version 5. I recently installed accumulo using the same. Here is the link for Cloudera manager 5. You can use this Youtube video as reference. 来源： https://stackoverflow.com/questions/21594680/accumulo-zookeeper-hadoop-installation-instructions-downloads-and-versions-for

问题 I currently have a setup with a single zookeeper node and Curator to access the data. Reading data is done through a Curator TreeCache. I have the following test: public void test_callback_successive_changes_success_global_new_version() throws InterruptedException { ZookeeperTestsHelper.createNewNodeInZookeeperSingleCommand("/my/path/new_node", "some string4", curator); ZookeeperTestsHelper.createNewNodeInZookeeperSingleCommand("/my/path/new_node", "some string5", curator); Thread.sleep(1000)

问题 I have a zookeeper instance (Solr integrated version) with 3 collections. Each collection has a different schema.xml in it's conf directory. Zookeeper starts sucessfully - the goal is to do a distributed search across the different collections. My problem is that when I look at the schema of collection2 and collection3 via the admin tool they both appear to be using collection1 schema. So I cannot update collections 2 & 3 as they are missing their correct fields. I have tried each of the
