HBase 能够连接到 ZooKeeper 但连接立即关闭
我正在运行一个 hadoop 项目四到五天，然后 hbase 出现错误：HBase 能够连接到 ZooKeeper 但连接立即关闭。这可能表明服务器有太多连接（默认为 30 个）。考虑检查 ZK 服务器日志中是否存在该错误，然后确保尽可能频繁地重用 HBaseConfiguration。有关详细信息，请参阅 HTable 的 javadoc。 请给我一些建议。多谢。
i'm running a hadoop project for four to five days,then an error from hbase : HBase is able to connect to ZooKeeper but the connection closes immediately. This could be a sign that the server has too many connections (30 is the default). Consider inspecting your ZK server logs for that error and then make sure you are reusing HBaseConfiguration as often as you can. See HTable's javadoc for more information.
Please give me some suggestion. Thanks a lot.

检查你的动物园管理员配置。 ZooKeeper 有一个设置来限制来自单个 IP 地址的连接数量，您可能需要修改它（如果这确实是问题所在）。该设置称为 maxClientCnxns
Check your zookeeper config. ZooKeeper has a setting to limit the number of connections from a single ip address and you may need to modify that (if that is indeed the problem). the setting is called maxClientCnxns
