描述mytable分区（…）
显示像mytable分区一样扩展的表（…）
使用从shell执行 hive -e '...' ####演示

create table mytable (i int) 
partitioned by (year int,month tinyint,day tinyint)
;

insert into mytable partition(year,month,day) values (1,2017,3,29)
;

hive> desc mytable partition (year=2017,month=3,day=29);
OK

res=`hive -e "use {db}; show partitions {table} partition(country='india',state='MH')"`

if [ ! -z "$res" ]; then
   do sth if the partition exists
fi

您可以为其他分区进行复制。

hive -e "use <db>; show partitions <table>;" egrep --color '<countryName>|<stateName>'

前任： hive -e "use db; show partitions table;" egrep --color 'India|MH' 这将为您提供所有匹配分区，其结果与india或mh或两者都匹配
