Solution

  • To load the file into hive, first copy the file to an HDFS Location. Like below:

    hadoop fs -put /complete_path_to_my_json/json_to_upload.json /app/hive/a_temp_location

    Then once you have the table created with JSON SerDe like below:

    create table if not exists my_json_table (id int, name string, designation string) row format serde 'org.apache.hive.hcatalog.d.JsonSerDe';

    You can load the data into the table with the following statement:

    load data inpath '/app/hive/a_temp_location/json_to_upload.json' into table my_json_table;
