創建hive整合hbase的表總結。例如以下兩種方式:
1、創建hive表的同步創建hbase的表
CREATE TABLE stage.hbase_news_company_content(key string comment "流水號", news_id string comment "新聞id", news_content string comment "文章內容") STORED BY 'org.apache.hadoop.hive.hbase.HBaseStorageHandler' WITH SERDEPROPERTIES ("hbase.columns.mapping" = ":key,cf1:news_id,cf1:news_content") TBLPROPERTIES("hbase.table.name" = "news_company_content");
這樣的方式創建hive表,刪除hive的表。hbase的表的數據也會被刪除
2、外表創建hive表整合hbase的表
須要先創建hbase的表:
create 'jsActionPage','cf1'
創建hive的外表
CREATE EXTERNAL TABLE ods.hbase_jsActionPage(key string, bdcCookieId string , pcScreenRatio string , pageCloseTime string , pageLoadCompleteTime string, pageOpenTime string, currentURL string) STORED BY 'org.apache.hadoop.hive.hbase.HBaseStorageHandler' WITH SERDEPROPERTIES ("hbase.columns.mapping" = ":key,cf1:bdcCookieId,cf1:pcScreenRatio, cf1:pageCloseTime, cf1:pageLoadCompleteTime, cf1:pageOpenTime, cf1:currentURL") TBLPROPERTIES("hbase.table.name" = "jsActionPage");
3、假設往hive整合hbase的表中插入數據
SQL方式:
insert into stage.hbase_news_company_content select a,b,c from stage.tracklog limit 15;
put 'jsActionPage','row1','cf1:time','20150818'
