hi
all In
my HDP cluster, I install 3 zookeeper-servers and zookeeper client on 3 nodes (
master1 , master2 , master3 ) ,. all nodes are on redhat machine version 7.2 When we run the zookeeper-client from master1 on the
zookeeper server on master1 , we get CONNECTING When we run the zookeeper-client from master1 on the
zookeeper server on master2 , we get CONNECTED When we run the zookeeper-client from master1 on the
zookeeper server on master3 , we get CONNECTED Examples [root@master1 ~]# /usr/hdp/current/zookeeper-client/bin/zookeeper-client -server master1:2181
Connecting to master1:2181
Welcome to ZooKeeper!
JLine support is enabled
[zk: master1:2181(CONNECTING) 0] <-- we get CONNECTING instead to get CONNECTED
[root@master1 ~]# /usr/hdp/current/zookeeper-client/bin/zookeeper-client -server master2:2181
Connecting to master2:2181
Welcome to ZooKeeper!
JLine support is enabled
WATCHER::
WatchedEvent state:SyncConnected type:None path:null
[zk: master2:2181(CONNECTED) 0]
[root@master1 ~]# /usr/hdp/current/zookeeper-client/bin/zookeeper-client -server master3:2181
Connecting to master3:2181
Welcome to ZooKeeper!

WATCHER::
WatchedEvent state:SyncConnected type:None path:null
[zk: master3:2181(CONNECTED) 0]
so problem is only on master1 machine , and actually client cant connected to the zookeeper server on machine - master1 What could be the reason for that? more /etc/zookeeper/2.6.4.0-91/0/zoo.cfg
clientPort=2181
syncLimit=15
autopurge.purgeInterval=24
maxClientCnxns=60
dataDir=/var/hadoop/zookeeper
initLimit=30
tickTime=2000
autopurge.snapRetainCount=30
server.1=master1.sys89.com:2888:3888
server.2=master2.sys89.com:2888:3888
server.3=master3.sys89.com:2888:3888
cat /usr/hdp/current/zookeeper-client/bin/zookeeper-client
#!/bin/bash
export ZOOKEEPER_HOME=/usr/hdp/2.6.4.0-91//zookeeper
export ZOOKEEPER_CONF=${ZOOKEEPER_HOME}/conf
export CLASSPATH=$CLASSPATH:$ZOOKEEPER_CONF:$ZOOKEEPER_HOME/*:$ZOOKEEPER_HOME/lib/*
export ZOOCFGDIR=${ZOOCFGDIR:-$ZOOKEEPER_CONF}
env CLASSPATH=$CLASSPATH ${ZOOKEEPER_HOME}/bin/zkCli.sh "$@"
we check the port 2181 and we get ok status
telnet localhost 2181
Trying ::1
