Section 7:62. Loading the Data into Hive Table from Local file system

To load data from a local file system into a Hive table, you can use the following steps:

1. Create an external table in Hive with the appropriate schema to match your data. You can do this using the CREATE EXTERNAL TABLE statement.
2. Move your data files to a location that can be accessed by the Hive cluster. This can be on the local file system or on a distributed file system like HDFS.
3. Use the LOAD DATA LOCAL INPATH statement to load the data into the Hive table. For example, 

LOAD DATA LOCAL INPATH ‘/home/user/data/mydata.txt’ INTO TABLE mytable;

Note that the LOCAL keyword is used to indicate that the data is located on the local file system. If your data is stored on a distributed file system like HDFS, you would omit the LOCAL keyword and use the HDFS path instead.

4. Once the data is loaded into the table, you can query it using standard Hive SQL statements.

Here’s an example of how you might create an external table in Hive and load data into it from a local file system:
