How about this ?
Assume you have a log file called
oompaloompa.log
TIMESTAMP=$(date +%Y_%m_%d_T%H_%M_%S);mv oompaloopa.log
oompaloopa.log.${TIMESTAMP};cat oompaloopa.log.${TIMESTAMP}| hdfs dfs -put -
/user/sasubramanian/oompaloopa.log.${TIMESTAMP}
This will directly put the file on HDFS and u can put it to the LOCATION
specified by your HIVE TABLE definition

Raj,
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.

Hi,
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.
Thanks,
Raj
