> Currently, only SELECT query could be put in EXPLAIN statement, and Drill does not support EXPLAIN CTAS statement.  
> One option would be to EXPLAIN the select_query in CTAS directly. However,   with the partition by clause added in CTAS,  it's not possible to do so any more, since there is no corresponding "PARTITION BY" clause in the SELECT query. 
> Therefore, it is important to extend EXPLAIN to accept CTAS directly.
