hbase表映射到hive

# 创建hbase表

hbase(main):087:0* create "test_hbase_mapping_hive", "f"
0 row(s) in 1.2400 seconds

=> Hbase::Table - test_hbase_mapping_hive

# put的数据

put "test_hbase_mapping_hive", "001","f:id","001"
put "test_hbase_mapping_hive", "001","f:name","luyi"

创建hbase到hive的映射表
# hive外表

create external table test_hbase_mapping_hive(rowkey string, id string, name string)  STORED BY 'org.apache.hadoop.hive.hbase.HBaseStorageHandler' WITH SERDEPROPERTIES ("hbase.columns.mapping" = "property:id, property:name") TBLPROPERTIES ("hbase.table.name" = "default:test_hbase_mapping_hive");

hbase的rowkey会默认映射到被映射的hive表的第一列，其他的qaulifier按照“hbase.columns.mapping”的顺序与hive表字段一一对应。

# hive内表

create external table test_hbase_mapping_hive(rowkey string, id string, name string)  STORED BY 'org.apache.hadoop.hive.hbase.HBaseStorageHandler' WITH SERDEPROPERTIES ("hbase.columns.mapping" = "property:id, property:name") TBLPROPERTIES ("hbase.table.name" = "default:test_hbase_mapping_hive");

hive外表与内表的区别：
删除映射后的hive表：
    外表：对hbase原始表没有影响；
    内表：删除hive同时，也会删除hbase原始表
