创建HBase的Hive外部表
1: create external table ttt(rowkey string,info map<string,string>)STORED BY 'org.apache.hadoop.hive.hbase.HBaseStorageHandler' WITH SERDEPROPERTIES ("hbase.columns.mapping" = ":key,info:") TBLPROPERTIES ("hbase.table.name" = "lwg");
报错，提示无法获得Zookeeper集群地址

在Hive命令行环境下，指定Zookeeper配置，能够正常访问Zookeeper、HBase
1: set hbase.zookeeper.quorum=zk1,zk2,zk3,zk4,zk5
2: set zookeeper.znode.parent=/hbase # hbase在zookeeper上root node
将这两个参数加入到~/.hiverc，这样hive在启动的时候，会自动加载给配置
