Step to reproduce the exception:
-------------------------------------------------
CREATE TABLE associateddata(creative_id int,creative_group_id int,placement_id
int,sm_campaign_id int,browser_id string, trans_type_p string,trans_time_p
string,group_name string,event_name string,order_id string,revenue
float,currency string, trans_type_ci string,trans_time_ci string,f16
map<string,string>,campaign_id int,user_agent_cat string,geo_country
string,geo_city string,geo_state string,geo_zip string,geo_dma string,geo_area
string,geo_isp string,site_id int,section_id int,f16_ci map<string,string>)
PARTITIONED BY(day_id int, hour_id int) ROW FORMAT DELIMITED FIELDS TERMINATED
BY '\t';

LOAD DATA LOCAL INPATH '/tmp/47rows.txt' INTO TABLE associateddata
PARTITION(day_id=20140814,hour_id=2014081417);

set hive.exec.dynamic.partition=true;
set hive.exec.dynamic.partition.mode=nonstrict;

CREATE EXTERNAL TABLE IF NOT EXISTS agg_pv_associateddata_c (
vt_tran_qty int COMMENT 'The count of view
thru transactions'
, pair_value_txt string COMMENT 'F16 name values
pairs'
)
PARTITIONED BY (day_id int)
ROW FORMAT DELIMITED FIELDS TERMINATED BY '\t'
STORED AS TEXTFILE
LOCATION '/user/prodman/agg_pv_associateddata_c';

INSERT INTO TABLE agg_pv_associateddata_c PARTITION (day_id)
select 2 as vt_tran_qty, pair_value_txt, day_id
from (select map( 'x_product_id',coalesce(F16['x_product_id'],'') ) as pair_value_txt , day_id , hour_id
from associateddata where hour_id = 2014081417 and sm_campaign_id in
(10187171,1090942,10541943,10833443,8635630,10187170,9445296,10696334,11398585,9524211,1145211)
) a GROUP BY pair_value_txt, day_id;

The query worked fine in Hive-0.12 and Hive-0.13. It starts failing in Hive-0.13. If hive.optimize.sort.dynamic.partition is turned off in Hive-0.13, the exception is gone.
