在Hive中创建索引

create table TBL_FACT_SYMBIAN_PACKET(PROVICE_FK  INT,DATE_FK  INT,MODEL_FK  INT,COUNTRY_FK  INT,NETWORK_FK  INT,OSLAG_FK  INT,OS_FK  INT,NQ_SOFTWARE_VER  INT,SUBCOOP_FK  INT,NQ_SOFTWARE_TYPE_FK  INT,SCANTYPE_FK  INT,SCANID  STRING,NAME  STRING,SECURITY  STRING,CA_ISSUER  STRING,CA_SUBJECT  STRING,HAS_NOTE  STRING,VIRUS_NAME  STRING
)partitioned BY(dt STRING) row format delimited fields terminated by '\t'

STORED AS textfile

load data local inpath '/home/boss/symbian_pkgs_20110529.log.hive' overwrite into table TBL_FACT_SYMBIAN_PACKET partition(dt='2011-05-29');

1 创建索引 
create index index_model_fk on table TBL_FACT_SYMBIAN_PACKET(model_fk) AS 'org.apache.hadoop.hive.ql.index.compact.CompactIndexHandler' WITH DEFERRED REBUILD ;

2. 更新数据 
ALTER INDEX index_model_fk ON TBL_FACT_SYMBIAN_PACKET REBUILD;

3. 删除索引
drop index index_model_fk on tbl_fact_symbian_packet;

4. 查看索引
show index on tbl_fact_symbian_packet;
