Eu instalo o zookeeper neste caminho /opt/zookeeper .
Meu zoo-1.cfg em /opt/zookeeper/conf/ :
#Node1

clientPort=2181
server.1=127.0.0.1:2888:3888
server.2=127.0.0.1:2889:3889
server.3=127.0.0.1:2890:3890
Meu log4j.properties em /opt/zookeeper/conf/ :
zookeeper.root.logger=DEBUG, SYSLOG8
log4j.rootLogger=${zookeeper.root.logger}
zookeeper.log.dir=/var/log/zookeeper
zookeeper.log.file=zookeeper.log
zookeeper.log.threshold=DEBUG

Quando quero me conectar com um cliente, recebo este erro:

Por favor, explique o motivo do erro. Também o que precisa ser feito para registrar logs do zookeeper no syslog? Obrigado.
Você tem log4j.appender.SYSLOG8 . Tem certeza de que não deveria ser log4j.appender.SYSLOG ?
Exemplo de bloco de configuração de blog.trifork. com :
log4j.rootLogger=INFO, SYSLOG
log4j.appender.SYSLOG=org.apache.log4j.net.SyslogAppender
log4j.appender.SYSLOG.syslogHost=127.0.0.1
log4j.appender.SYSLOG.layout=org.apache.log4j.PatternLayout

Meu problema foi resolvido. Houve um problema ao usar o arquivo de configuração padrão.

Este arquivo usa variável! Eu removo todas as variáveis e apenas insiro rsyslog code também eu verifico ROLLINGFILE e tudo bem. Você pode até encontrar este arquivo neste log4j .
Então, eu apaguei todas as variáveis e coloquei apenas o código original.
