Hi shaik
Step 1
Create an external table with the desired location in hdfs. Your data files for
the hive table will be stored in this location/directory in hdfs.
Step 2
Now use the LOAD DATA command to load data from any other location into this
table. On successful execution of this command the data files will be moved to
the table's location .( specified in previous step)
Alternatively you can move or copy files within hdfs using hadoop fs copy
commands.
