You should dump the data in a temp table first and then move the data into final table with select query.
Select date(), c1,c2..... From temp table.
Reason: we should avoid custom operation in load unless it is necessary.

Can any one please suggest the best way to do the following in Hive?
Load 'todays date stamp' + << ALL FIELDS C1,C2,C3,C4 IN A FILE F1 >> to a Hive table T1 ( D1,C1,C2,C3,C4)
Can the following command be modified in some way to acheive the above
hive > load data local inpath '/software/home/hadoop/dat_files/' into table T1;
My requirement is to append a date stamp to a Web log file and then load it to Hive table.
