Create source table
------------------
CREATE EXTERNAL TABLE testmove (
a string,
b string
)
PARTITIONED BY (cust string, dt string);
Data has been kept in /usr/hive/warehouse/testmove/cust=a/dt=20100102/a.txt
a.txt has 1 row the value is "a", "b"
Create Destination table
-----------------------
CREATE EXTERNAL TABLE testmove1 (
a string,
b string
)
PARTITIONED BY (cust string, dt string)
Run the query for dynamic partion insert
---------------------------------------
set hive.exec.dynamic.partition=true;
set hive.exec.dynamic.partition.mode=nonstrict;
FROM testmove t
INSERT OVERWRITE TABLE testmove1 PARTITION (cust, dt)
SELECT t.a, t.b, 'a', '20100102';

OK
If i run as static partion is the data is inserted in to destination table.
FROM testmove t
INSERT OVERWRITE TABLE testmove1 PARTITION (cust='a', dt='20100102')
SELECT t.a, t.b;
