Sir, One quick question, what if ascii delimited file and table structure not match if still can we load data? Like if hive table have one column but ascii file do not have that column value present, then How can identity or cast that particular column in hive table in a way that if value not present in file then can load value as null in hive table for that specific column into hive table. I am facing this scenario and looking for any solution if we can present. Appreciate your response.
