我们系统在生产上的配置如下，仅供参考
Configuration configuration = new Configuration();
configuration.set("hbase.zookeeper.quorum", quorum);
configuration.set("hbase.client.scanner.caching", "500");// 所有客户端的默认scan缓存时间， 默认100
configuration.set("hbase.client.pause", "50");// 失败重试时等待时间， 默认100
configuration.set("hbase.rpc.timeout", "2000");// 一次RPC请求的超时时间， 默认60000
configuration.set("hbase.client.operation.timeout", "3000");// 客户端发起一次数据操作直至得到响应之间总的超时时间， 默认Integer.MAX_VALUE（一次阻塞操作）
configuration.set("hbase.client.retries.number", "3");// 重试次数3次，默认31
