@@ -51,6 +51,9 @@ Spark SQL supports the vast majority of Hive features,
such as:
* Explain
* Partitioned tables including dynamic partition insertion
* View
+ * If column aliases are not specified in view definition queries, both
Spark and Hive will
+ generate alias names, but in different ways. In order for Spark to be
able to read views created
+ by Hive, users should explicitly specify column aliases in view
definition queries.
