apache - zookeeper无法打开localhost/0的套接字:0:0:0:0:0:0:1:2181

Question

我正在将Zookeeper集成用于hbase。 Zookeeper正在3台计算机上运行。而HBase也处于完全分布式模式。我有Nutch 2.x版本。当我开始获取一些数据时，它会在日志日志文件中显示以下错误。

ERROR zookeeper.ClientCnxnSocketNIO - Unable to open socket to localhost/0:0:0:0:0:0:0:1:2181
2015-01-23 16:34:21,956 WARN  zookeeper.ClientCnxn - Session 0x0 for server null, unexpected error, closing socket connection and attempting reconnect

当我在三个Zookeeper实例上运行命令时

echo ruok | nc 1.1.1.1 2181 it says imok

怎么了我的hbase版本是0.94.14，Zookeeper版本是3.4.5，solr版本4.10.3(用于索引)和Nutch版本是2.2.3。

(CentOS)检查您的/etc/hosts文件，以及是否包含

127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6

之类的文件
将其更改为

127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         ip6-localhost ip6-localhost.localdomain localhost6 localhost6.localdomain6
