Dynamic Partitioning + CREATE AS on HIVE

Question

I'm trying to create a new table from another table with CREATE AS and dynamic Partitioning on HiveCLI. I'm learning from Hive official wiki where there is this example:

 CREATE TABLE T (key int, value string) 
 PARTITIONED BY (ds string, hr int) AS
 SELECT key, value, ds, hr+1 hr1 
   FROM srcpart 
   WHERE ds is not null 
   And hr>10;

But I received this error:

FAILED: SemanticException [Error 10065]:

CREATE TABLE AS SELECT command cannot specify the list of columns for the target table

Answer 1

Since you already know the full schema of the target table, try creating it first and the populating it with a LOAD DATA command:

SET hive.exec.dynamic.partition.mode=nonstrict;

CREATE TABLE T (key int, value string) 
PARTITIONED BY (ds string, hr int);

INSERT OVERWRITE TABLE T PARTITION(ds, hr) 
SELECT key, value, ds, hr+1 AS hr 
   FROM srcpart 
   WHERE ds is not null 
   And hr>10;

Note: the set command is needed since you are performing a full dynamic partition insert.

Answer 2

SET hive.exec.dynamic.partition.mode=nonstrict;

CREATE TABLE T (key int, value string) 
PARTITIONED BY (ds string, hr int);

INSERT OVERWRITE TABLE T PARTITION(ds, hr) 
SELECT key, value, ds, hr+1 AS hr 
FROM srcpart 
WHERE ds is not null 
      And hr>10;

In the above code, instead of the Create statement use: CREATE TABLE T like srcpart;

In case the partitioning is similar.
