How to load the data from HDFS to hive table - hive

Question

Please tell me how to load the data from HDFS to hive table?? Because I lost the tweets which downloaded yesterday.
To load the data I used following.
LOAD DATA LOCAL INPATH '/user/hue/twitter/tweets/2017/03/10'
OVERWRITE INTO TABLE tweets
PARTITION (datehour=20170310).
Give me a correct query This is my table.I send it as two steps
CREATE EXTERNAL TABLE twitter.tweets (
id BIGINT,
created_at STRING,
source STRING,
favorited BOOLEAN,
retweeted_status STRUCT<
text:STRING,
user:STRUCT < screen_name:STRING, name:STRING >,
retweet_count:INT
>,
entities STRUCT<
urls:ARRAY<STRUCT<expanded_url:STRING>>,
user_mentions:ARRAY<STRUCT <
screen_name:STRING,
name:STRING
>
>,
hashtags:ARRAY<STRUCT<text:STRING>>
>,
text STRING,
–user STRUCT<
screen_name:STRING,
name:STRING,
friends_count:INT,
followers_count:INT,
statuses_count:INT,
verified:BOOLEAN,
utc_offset:INT,
time_zone:STRING
>,
in_reply_to_screen_name STRING )
PARTITIONED BY (datehour INT)
ROW FORMAT SERDE 'com.cloudera.hive.serde.JSONSerDe'
LOCATION '/twitter';
The sample data : atttached just little
{"filter_level":"low","retweeted":false,"in_reply_to_screen_‌​name":null,"possibly‌​_sensitive":false,"t‌​runcated":false,"lan‌​g":"en","in_reply_to‌​_status_id_str":null‌​,"id":84064934204214‌​8865,"extended_entit‌​ies":{"media":[{"siz‌​es":{"thumb":{"w":15‌​0,"resize":"crop","h‌​":150},"small":{"w":‌​340,"resize":"fit","‌​h":340},"medium":{"w‌​":600,"resize":"fit"‌​,"h":600},"large":{"‌​w":960,"resize":"fit‌​","h":960}},"source_‌​user_id":15934076,
I found that to load the data from HDFS to hive table is,
LOAD DATA INPATH '/user/hue/twitter/tweets/2017/03/10' OVERWRITE INTO TABLE tweets PARTITION (datehour=20170310).
Is this correct and will I lost my source file?? If so what is the solution query??
