Exception in thread "main" org.apache.hadoop.hbase.ZooKeeperConnectionException: 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.

这个错误说明eclipse没有连接到zookeeper，在程序中添加zookeeper配置信息即可，具体如下：
Configuration conf=HBaseConfiguration.create();
conf.set("hbase.zookeeper.quorum","192.168.0.118, 192.168.0.186, 192.168.0.182");
conf.set("hbase.zookeeper.property.clientPort","2222");
