问题 I am new to Zookeeper and it has being a real issue to install it and run. I am not sure what is wrong in here but I will explain what I've being doing to make it more clear: 1.- I've followed the installation guide provided by Apache. This means download the Zookeeper distribution (stable release) extracted the file and moved into the home directory. 2.- As I am using Ubuntu 12.04 I've modified the .bashrc file including this: export ZOOKEEPER_INSTALL=/home/myusername/zookeeper-3.4.5 export

问题 I just tried to connect to hbase which is part of the cloudera-vm using a java client. (192.168.56.102 is the inet ip of the vm) I use virtual box with host only network setting. So I can access the webUI of the hbase master @ http://192.168.56.102:60010/master.jsp Also my java client (worked well on the vm itself) established connection to 192.168.56.102:2181 But when it calls getMaster I get connection refused see log: 11/09/14 11:19:30 INFO zookeeper.ZooKeeper: Initiating client connection

问题 I'm following http://jayatiatblogs.blogspot.com/2011/11/storm-installation.html & http://zookeeper.apache.org/doc/r3.3.3/zookeeperAdmin.html#sc_zkMulitServerSetup to set up Apache Storm cluster in Ubuntu 14.04 LTS at AWS EC2. My master node is 10.0.0.185. My slave nodes are 10.0.0.79, 10.0.0.124 & 10.0.0.84 with myid of 1, 2 and 3 in their zookeeper-data respectively. I set up an ensemble of Apache Zookeeper consists of all the 3 slave nodes. Below are my zoo.cfg for my slave nodes: tickTime

问题 I am new to zookeeper and distributed systems, and am learning it myself. From what I understand for now, it seems that ZooKeeper is simply a key-value store whose keys are paths and values are strings, which is nothing different from, say, Redis. (And apparently we can use slash-separated path as keys in redis as well.) So my question is, what is the essential difference between ZooKeeper and other distributed KV store? Why is ZooKeeper using so called "paths" as keys, instead of simple

问题 I'm using confluent platform, the zookeeper is active with status lookup. but when I try to start kafka with confluent it shows zookeeper is down. $ sudo service zookeeper status Redirecting to /bin/systemctl status zookeeper.service ● zookeeper.service - Zookeeper Loaded: loaded (/etc/systemd/system/zookeeper.service; disabled; vendor preset: disabled) Active: active (running) since Tue 2017-08-08 17:25:34 PDT; 16h ago Docs: http://kafka.apache.org/documentation.html Process: 3774 ExecStop=

问题 I am now using a CDH-5.3.1 cluster with three zookeeper instances located in three ips: 133.0.127.40 n1 133.0.127.42 n2 133.0.127.44 n3 Everything works fine when it starts, but these days I notice that the node n2 keeps getting the WARN: caught end of stream exception EndOfStreamException: Unable to read additional data from client sessionid **0x0**, likely client has closed socket at org.apache.zookeeper.server.NIOServerCnxn.doIO(NIOServerCnxn.java:220) at org.apache.zookeeper.server

问题 We have a standalone zookeeper setup on a dev machine. It works fine for every other dev machine except this one testdev machine. We get this error over and over again when trying to connect to zookeeper through testdev: 2012-11-09 14:06:53,909 - INFO [main-SendThread(zk01.dev.bunchball.net:2181):ClientCnxn$SendThread@947] - Socket connection established to zk01.dev.bunchball.net/192.168.8.58:2181, initiating session 2012-11-09 14:06:53,911 - INFO [main-SendThread(zk01.dev.bunchball.net:2181)

问题 Closed. This question is off-topic. It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed 3 years ago . ZooKeeper is a highly available coordination service for data centers. It originated in the Hadoop project. One can implement locking, fail over, leader election, group membership and other coordination issues on top of it. Are there any alternatives to ZooKeeper? (free software of course) 回答1: I've looked

问题 I created a topic in my local kafka cluster with 3 servers / brokers by running the following from my kafka installation directory bin/kafka-topics.sh --create --zookeeper localhost:2181 --replication-factor 2 --partitions 2 --topic user-activity-tracking-pipeline Everything worked fine as I was able to produce and consumer messages from my topic. After restarting my machine, I started bundled zookeeper from kafka installation directory by running the following in the terminal bin/zookeeper
