【hbase】hbase客户端连接zookeeper接过多问题

问题原因：

客户端程序通过zookeeper访问hbase的连接数超过设置的默认链接数(默认数是60)，连接数不够用会导致后续的连接连接不上去。

解决办法：

1. 设置hbase-site.xml配置文件

添加如下属性

<property>

<name>hbase.zookeeper.property.maxClientCnxns</name>

<value>300</value>

<description>Property from ZooKeeper's config zoo.cfg.

Limit on number of concurrent connections (at the socket level) that a

single client, identified by IP address, may make to a single member of

the ZooKeeper ensemble. Set high to avoid zk connection issues running

standalone and pseudo-distributed.

</description>

</property>

2. 配置zoo.cfg

maxClientCnxns=300

重启下zookeeper，hbase,重新测试，问题解决。
