Date variable is NULL while loading csv data into hive External table - csv

Question

I am trying to load a SAS Dataset to Hive external table. For that, I have converted SAS dataset into CSV file format first. In sas dataset, Date variable (i.e as_of_dt) contents shows this:
LENGTH=8 , FORMAT= DATE9. , INFORMAT=DATE9. , LABLE=as_of_dt
And for converting SAS into CSV, I have used below code patch (i have used 'retain' statement before in sas so that the order of variables are maintained):
proc export data=input_SASdataset_for_csv_conv
outfile= "/mdl/myData/final_merged_table_201501.csv"
dbms=csv
replace;
putnames=no;
run;
Till here (i.e till csv file creation), the Date variable is read correctly. But after this, when I am loading it into Hive External Table by using below command in HIVE, then the DATE variable (i.e as_of_dt) is getting assigned as NULL :
CREATE EXTERNAL TABLE final_merged_table_20151(as_of_dt DATE, client_cm_id STRING, cm11 BIGINT, cm_id BIGINT, corp_id BIGINT, iclic_id STRING, mkt_segment_cd STRING, product_type_cd STRING, rated_company_id STRING, recovery_amt DOUBLE, total_bal_amt DOUBLE, write_off_amt DOUBLE) ROW FORMAT DELIMITED FIELDS TERMINATED BY ',' STORED AS TEXTFILE LOCATION '/mdl/myData';
Also, when i am using this command in hive desc formatted final_merged_table_201501, then I am getting following table parameters:
Table Parameters:
COLUMN_STATS_ACCURATE false
EXTERNAL TRUE
numFiles 0
numRows -1
rawDataSize -1
totalSize 0
transient_lastDdlTime 1447151851
But even though it shows numRows=-1, still I am able to see data inside the table, by using hive command SELECT * FROM final_merged_table_20151 limit 10; , with Date variable (as_of_dt) stored as NULL.
Where might be the problem?

Based on madhu's comment you need to change the format on as_of_dt to yymmdd10.
You can do that with PROC DATASETS. Here is an example:
data test;
/*Test data with AS_OF_DT formatted date9. per your question*/
format as_of_dt date9.;
do as_of_dt=today() to today()+5;
output;
end;
run;
proc datasets lib=work nolist;
/*Modify Test Data Set and set format for AS_OF_DT variable*/
modify test;
attrib as_of_dt format=yymmdd10.;
run;
quit;
/*Create CSV*/
proc export file="C:\temp\test.csv"
data=test
dbms=csv
replace;
putnames=no;
run;
If you open the CSV, you will see the date in YYYY-MM-DD format.
