Hello everyone, I know that there are already several topics here about my doubt, the point is that, none resolved. I have the following situation. I was able to get twitter data via flume. They are already on HDFS. But I can not turn them into Hive tables. the path of my files is in: /usr/root/flume/test
File: FlumeData.1505877214590 the header of my file in hdfs is as follows: Header: ------------------------------------------------------------------------------- {"type":"record","name":"Doc","doc":"adoc","fields":[{"name":"id","type":"string"},{"name":"user_friends_count","type":["int","null"]},{"name":"user_location","type":["string","null"]},{"name":"user_description","type":["string","null"]},{"name":"user_statuses_count","type":["int","null"]},{"name":"user_followers_count","type":["int","null"]},{"name":"user_name","type":["string","null"]},{"name":"user_screen_name","type":["string","null"]},{"name":"created_at","type":["string","null"]},{"name":"text","type":["string","null"]},{"name":"retweet_count","type":["long","null"]},{"name":"retweeted","type":["boolean","null"]},{"name":"in_reply_to_user_id","type":["long","null"]},{"name":"source","type":["string","null"]},{"name":"in_reply_to_status_id","type":["long","null"]},{"name":"media_url_https","type":["string","null"]},{"name":"expanded_url","type":["string","null"]}]} ------------------------------------------------------------------------------- I've tried the script below, or other variants of it and nothing. ------------------------------------------------------------------------------- CREATE EXTERNAL TABLE tweets (
