主题: Loading data from HDFS to hive and leading to many NULL value in hive table
I am confusing about the following result. Why the hive table has so many NULL value ?
hive> select * from managers;
OK

woodji01m,CH1,28,19,9,9NULLNULLNULLNULLNULL

This is my create table code : create table managers (managerID string, teamID string, g int, w int, l int, x int);
managers.txt in HDFS structure

Loading data from HDFS to hive code
LOAD DATA INPATH '/managers.txt' OVERWRITE TABLE managers;
What’s wrong with these NULL value?
