【问题描述】：
在访问远程 hbase 服务器时，我的 java hbase 客户端出现上述错误。我在构建路径中设置了所有必需的 jar 文件，还从 web ui hbase-site.xml 复制了所需的配置详细信息。但我不知道出了什么问题。我无权访问远程 hadoop/hbase/zookeeper 配置。我从
中找到了一些建议http://marcin.cylke.com.pl/blog/2013/03/21/zookeeper-tips/
在 m 下面提供代码 sn-p 以及堆栈跟踪。
代码
Configuration config = HBaseConfiguration.create();
config.clear();
config.addResource("hbase-site.xml");
config.set("hbase.zookeeper.quorum","10.***.2.231");
config.set("hbase.zookeeper.property.clientPort","22");
config.set("hbase.master", "10.***.1.232:60000");
//config.set("hbase.zookeeper.property.maxClientCnxns","300");
HTable table = new HTable(config, "WB4213");
Scan scan = new Scan();
ResultScanner scanner = table.getScanner(scan);
堆栈跟踪

我不确定，但您的 Clint 服务器连接似乎有问题，因为它清楚地表明
.ClientCnxn: Session 0x0 for server 10.241.1.231/10.241.1.231:22, unexpected error, closing socket connection，请不要公开分享您的 IP -
那是因为 I/O 异常 len1397966893 超出范围！ @smn_onrocks
