Impostazione di una singola istanza Zookeeper e l'associazione non riesce

Question

Sto provando a impostare una singola istanza di zookeeper utilizzando la configurazione seguente, tuttavia il log di inizio indica che il zookeeper si blocca durante il tentativo di associare la porta 2181. Qualcuno per favore fammi sapere il problema qui. Grazie.

Answer 1

vorrei ricordare che quando si ottiene il seguente messaggio di registrazione significa che il server è effettivamente iniziato.

INFO [main:NIOServerCnxnFactory@94] - binding to port 0.0.0.0/0.0.0.0:2181 

Anche il messaggio di errore che si vede se si dispone di una singola istanza di guardiano dello zoo, come di seguito è in realtà un avvertimento piuttosto che un errore.

2014-07-18 16:00:48,980 [myid:] - ERROR [main:QuorumPeerConfig@289] - Invalid configuration, only one server specified (ignoring) 

Answer 2

suggerisco di rimuovere la seguente riga dal file di configurazione

server.1=localhost:2888:3888 

e quindi riavviare il server.

Answer 3

Stai eseguendo il controllo su Windows 64 bit. Stavo avendo lo stesso problema ma poi ho capito che Win64 non è supportato. Vedi il link Zookeeper http://zookeeper.apache.org/doc/r3.4.5/zookeeperAdmin.html#sc_supportedPlatforms

Answer 4

Prova ad aggiungere questo al zoo.cfg quorumListenOnAllIPs=true
