새 3.5 Zookeeper 노드가 내 클러스터에 동적으로 추가되지 않는 것 같습니다.

Question

Zookeeper 버전 : 3.5.3-beta를 사용 중이며 표준 3 노드 구성으로 구성했습니다. 이제는 문서에 따라 3 개의 노드를 추가하려고합니다.하지만 새 노드는 옵저버로 동적으로 추가되는 것처럼 보이지 않습니다 (https://zookeeper.apache.org/doc/trunk/zookeeperReconfig.html#ch_reconfig_dyn 참조).

먼저 다음 설정을 사용하여 첫 번째 노드를 추가하려고 시도했습니다 : "ZOOKEEPER_IP_LIST=10.144.81.81 10.144.81.83 10.144.81.86 10.144.46.54",하지만 클러스터에 가입하지 않습니다. 새 노드를 시작할 때 다음과 같은 메시지가 나타나며 클러스터의 3 개 노드 만 표시합니다. 심지어 새로운 노드를 포함하기 위해 3 개의 초기 노드를 다시 시작하려고했지만 여전히 이전 구성을 반영했습니다.

clientPort=2181 
secureClientPort=-1 
dataDir=/dbpath/data/version-2 
dataDirSize=134254305 
dataLogDir=/dbpath/data/version-2 
dataLogSize=134254305 
tickTime=2000 
maxClientCnxns=30 
minSessionTimeout=4000 
maxSessionTimeout=40000 
serverId=3 
initLimit=60 
syncLimit=5 
electionAlg=3 
electionPort=3888 
quorumPort=2888 
peerType=0

server.1=10.144.81.83:2888:3888:participant 
server.2=10.144.81.86:2888:3888:participant 

그게 내가 위의 노력 구성이 REST 인터페이스의 결과와 일치하는지 먼저 리더에 zkCli.sh 명령을 사용하기로 결정 작동하지 않았다

, 그것은했다.

$ sudo bin/zkCli.sh -server 10.144.81.83:2181 config

나는 다음 다시 구성하고 하나 개의 새로운 노드를 추가 zkCli.sh을 사용하려고하지만, 내가 ACL을 구성하지 않았거나 내가 그 아는 모든 인증이 발생할 수있어 혼란 인 인증 문제를 발생 이 오류.

는 난 그냥 특정 노드 구성을 변경하지 않고 새로운 토폴로지 변경을 지정할 수, 하나 바르게 또는 잘못, 문서로 인상했다. 은을 선호하지만 zkCli를 사용하지 않기 때문에 배포 프로세스가 복잡해지기 때문에 사용하지 않으면됩니다.

Answer 1

새로운 관찰자는 사육사가 설정에 대한 정보를 유지하는 경로가 허용되지 않습니다. 처음에는 모든 노드는 정적 설정에 자신을 추가하지만 경로에 권한이 없기 때문에 동적 새로운 노드가 허용되지 않습니다 (/config)

당신이 JVM 옵션으로 노드를 다시 시도 할 수 있습니다 :

-Dzookeeper.skipACL=true 

또는 당신이 될 수 있습니다 수퍼 유저 :

$ export ZK_CLASSPATH=/etc/zookeeper/conf/:/usr/hdp/current/zookeeper-server/lib/*:/usr/hdp/current/zookeeper-server/* 
$ java -cp $ZK_CLASSPATH org.apache.zookeeper.server.auth.DigestAuthenticationProvider super:super123 

출력 :

super:super123->super:UdxDQl4f9v5oITwcAsO9bmWgHSI= 

,536,

다음 루트로 :

$ export SERVER_JVMFLAGS=-Dzookeeper.DigestAuthenticationProvider.superDigest=super:UdxDQl4f9v5oITwcAsO9bmWgHSI= 
$ bin/zkCli.sh -server 10.144.81.83:2181 reconfig -file ../newconfig.cfg.dynamic
