Redash send query like the following with comment to Athena

/* Username */ MSCK REPAIR TABLE table_name;

which leads to syntax error,

Your query has the following error(s):
FAILED: ParseException line 1:0 cannot recognize input near ‘/’ ‘*’ ‘Username’

I am using the latest redash image on docker hub (id: 779aa01f1cde).

Only partition recover query will fail, SELECT query works fine with the comment annotation.
