dilipbiswal opened a new pull request #24224: [SPARK-27285] Support describing output of CTE
URL: https://github.com/apache/spark/pull/24224
 
 
   ## What changes were proposed in this pull request?
   SPARK-26982 allows users to describe output of a query. However, it had a limitation of not supporting CTEs due to limitation of the grammar having a single rule to parse both select and inserts. After SPARK-27209, which splits select and insert parsing to two different rules, we can now support describing output of the CTEs easily.
   
   ## How was this patch tested?
   Existing tests were modified.
