Hive映射Hbase表的几种方式

1.Hive内部表，语句如下

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16

CREATE TABLE ods.s01_buyer_calllogs_info_ts( key string comment "hbase rowkey", buyer_mobile string comment "手机号", contact_mobile string comment "对方手机号", call_date string comment "发生时间", call_type string comment "通话类型", init_type string comment "0-被叫,1-主叫", other_cell_phone string comment "对方手机号", place string comment "呼叫发生地", start_time string comment "发生时间", subtotal string comment "通话费用", use_time string comment "通话时间（秒）" ) STORED BY 'org.apache.hadoop.hive.hbase.HBaseStorageHandler'     WITH SERDEPROPERTIES ("hbase.columns.mapping" = ":key,record:buyer_mobile,record:contact_mobile,record:call_date,record:call_type,record:init_type,record:other_cell_phone,record:place,record:start_time,record:subtotal,record:use_time")     TBLPROPERTIES("hbase.table.name" = "s01_buyer_calllogs_info_ts");

   建好表之后，进入hbase shell执行list能看到表s01_buyer_calllogs_info_ts，hive drop掉此表时，hbase也被drop。

2.Hive外部表，语句如下，

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18

create 'buyer_calllogs_info_ts', 'record', {SPLITS_FILE => 'hbase_calllogs_splits.txt'}   CREATE EXTERNAL TABLE ods.s10_buyer_calllogs_info_ts( key string comment "hbase rowkey", buyer_mobile string comment "手机号", contact_mobile string comment "对方手机号", call_date string comment "发生时间", call_type string comment "通话类型", init_type string comment "0-被叫,1-主叫", other_cell_phone string comment "对方手机号", place string comment "呼叫发生地", start_time string comment "发生时间", subtotal string comment "通话费用", use_time string comment "通话时间（秒）" )     STORED BY 'org.apache.hadoop.hive.hbase.HBaseStorageHandler'     WITH SERDEPROPERTIES ("hbase.columns.mapping" = ":key,record:buyer_mobile,record:contact_mobile,record:call_date,record:call_type,record:init_type,record:other_cell_phone,record:place,record:start_time,record:subtotal,record:use_time")     TBLPROPERTIES("hbase.table.name" = "buyer_calllogs_info_ts");

   从方式需要先在hbase建好表，然后在hive中建表，hive drop掉表，hbase表不会变。

3.Hive映射HBase的列族

CREATE EXTERNAL TABLE hiveFromHbase(
rowkey string,
f1 map,
f2 map,
f3 map
) STORED BY 'org.apache.hadoop.hive.hbase.HBaseStorageHandler'
WITH SERDEPROPERTIES ("hbase.columns.mapping" = ":key,f1:,f2:,f3:")
TBLPROPERTIES ("hbase.table.name" = "hbase_test");

hive> select * from hiveFromHbase;
OK
r1      {"name":"zhangsan"}     {"age":"20"}    {"sex":"male"}
r2      {"name":"lisi"} {"age":"30"}    {"sex":"female"}
r3      {"name":"wangwu"}       {"age":"40"}    {"sex":"male"}
