1,创建hive表

分区

分桶

压缩

事务支持

create table if not exists radiusc(
UserName string,
PublicIP string,
PrivateIP string,
BeginPort string,
EndPort string,
OnlineState string,
OnlineTime string,
OfflineTime string,
MacAddress string,
OfflineReason string
)
comment 'adr information'
partitioned by (day string, hour string)
CLUSTERED BY (PublicIP) INTO 4 BUCKETS
row format delimited fields terminated by '|' lines terminated by '\n'
stored as ORC TBLPROPERTIES ("orc.compress"="SNAPPY",'transactional'='true');

2,hive-site.xml
