Introduction

Ce document décrit ZooKeeper, qui est essentiellement un service centralisé pour les systèmes distribués à un magasin de valeurs de clé hiérarchique. Il est utilisé pour fournir un service de configuration distribuée, un service de synchronisation et un registre d'attribution de noms pour les grands systèmes distribués. L'architecture de ZooKeeper prend en charge la haute disponibilité par le biais de services redondants. Les clients peuvent ainsi demander à un autre responsable ZooKeeper si le premier ne répond pas. Les noeuds ZooKeeper stockent leurs données dans un espace de noms hiérarchique, un peu comme un système de fichiers ou une structure de données arborescente. Les clients peuvent lire et écrire sur les noeuds et ainsi disposer d'un service de configuration partagé. ZooKeeper peut être vu comme un système de diffusion atomique par lequel les mises à jour sont totalement ordonnées.

ZooKeeper offre les fonctionnalités suivantes :

- Système fiable : le système est très fiable car il fonctionne toujours même en cas de défaillance d’un noeud.

- Architecture simple : l'architecture de ZooKeeper est assez simple. il utilise un espace de noms hiérarchique partagé, qui aide à la coordination des processus.

- Traitement rapide : ZooKeeper est particulièrement rapide pour les charges de travail dominantes en lecture.

- Évolutif : les performances de ZooKeeper peuvent être améliorées par l'ajout de noeuds.

Dans HX, il existe cette implémentation spécifique :

- Le service appelé expositor gère le démarrage/arrêt du zookeeper.

- Les processus du cluster HX sont des clients de Zookeeper et communiquent via le port tcp 2181 ex storfs, stmgr, etc.

- Les systèmes comportant plus de cinq noeuds disposent de certains noeuds autonomes. Les systèmes comportant cinq noeuds ou moins ne doivent jamais avoir de noeud autonome.

- Nombre minimum de noeuds requis pour Quorum = N/2 +1.

Par exemple, pour un cluster à trois noeuds - N/2=1,5 arrondi à 1 +1 = 2 (une seule défaillance de noeud peut être tolérée)

Par exemple, pour un cluster à cinq noeuds - N/2=2,5 arrondi à 2 +1 = 3 (seules deux défaillances de noeud peuvent être tolérées)

Puisque vous ne faites que cinq noeuds pour un cluster ZK, vous ne tolérez qu'un maximum de deux échecs de noeud pour un nombre quelconque de noeuds dans le cluster. C'est vrai pour les noeuds convergents.

Service Zookeeper de requête

Le Zookeeper possède une syntaxe de commande à quatre lettres qui vous permet d'interroger l'état, les connexions de liste, le nombre de znoeuds, etc.

Vérifiez l'état du zookeeper sur le noeud local - (plan ==> OK ?. imok==>Je suis OK).

Vérifiez si le zookeeper est un leader ou un suiveur.
