Introduction

Este documento descreve o ZooKeeper, que é essencialmente um serviço centralizado para sistemas distribuídos em um armazenamento hierárquico de valor-chave. É usado para fornecer um serviço de configuração distribuída, serviço de sincronização e registro de nomes para grandes sistemas distribuídos. A arquitetura do ZooKeeper oferece suporte à alta disponibilidade por meio de serviços redundantes. Os clientes podem perguntar a outro líder do ZooKeeper se o primeiro não responder. Os nós do ZooKeeper armazenam seus dados em um espaço de nomes hierárquico, como um sistema de arquivos ou uma estrutura de dados de árvore. Os clientes podem ler e gravar nos nós e, dessa forma, têm um serviço de configuração compartilhado. O ZooKeeper pode ser visto como um sistema de transmissão atômica através do qual as atualizações são totalmente solicitadas.

O ZooKeeper oferece os seguintes recursos principais:

Sistema confiável - O sistema é muito confiável porque continua funcionando mesmo se um nó falhar.
Arquitetura simples - A arquitetura do ZooKeeper é bastante simples; ele usa um namespace hierárquico compartilhado, o que ajuda na coordenação de processos.
Processamento rápido - o ZooKeeper é especialmente rápido em cargas de trabalho dominantes de leitura.
Escalável - O desempenho do ZooKeeper pode ser melhorado pela adição de nós.

Na HX, há essa implementação específica:

O Serviço chamado exibidor gerencia a inicialização/desligamento do zookeeper.
Os processos no cluster HX são clientes para o Zookeeper e se comunicam através da porta tcp 2181 ex storfs, stmgr e assim por diante.
Sistemas com mais de cinco nós terão alguns nós autônomos. Sistemas com cinco nós ou menos nunca devem ter um nó autônomo.
O número mínimo de nós exigido para quorum = N/2 +1.

Por exemplo, para um cluster de três nós - N/2=1,5 Arredondado para 1 +1 =2 (somente uma falha de nó pode ser tolerada)

Por exemplo, para um cluster de cinco nós - N/2=2,5 arredondado para 2 +1 =3 (somente duas falhas de nó podem ser toleradas)

Como você só faz cinco nós para um cluster ZK, você tolera apenas um máximo de duas falhas de nó para qualquer número de nós no cluster. Isso é verdade para nós convergentes.

Verificar o status do serviço do monitor

Serviço de Zookeeper de Consulta

O Zookeeper tem uma sintaxe de comando de quatro letras que permite consultar o status, listar conexões, número de nós zetc.

Verifique o status do zookeeper no nó local - (ruok ==> Você está bem?. imok==>Estou bem).

root@SpringpathControllerMSH7NHXRFL:/var/log/zookeeper# echo ruok|nc localhost 2181
imok

Verificar se o tratador é um líder ou um seguidor.
