1.	What are Skewed tables in Hive?
Answer» Skewed tables are a type of table in which some VALUES in a COLUMN appear more frequently than others. The distribution is skewed as a result of this. When a table is created in Hive with the SKEWED option, the skewed values are written to separate files, while the REMAINING data are written to ANOTHER file.
