                 Key: IMPALA-12652

             Project: IMPALA
          Issue Type: Improvement

            Reporter: Jason Fehr
            Assignee: Jason Fehr


Implement a coordinator startup flag that limits the max length (number of 
characters) of the insert DML statement that inserts records into the 
impala_query_log table.

The purpose of this flag is to ensure that workload management does not 
generate an insert DML statement that exceeds Impala's max length for a sql 
statement (approximately 16 megabytes or 16 million characters).
