File fe/src/main/cup/sql-parser.cup:

PS1, Line 1033: CreateTableStmt.CreateTableAsSelectStmt
maybe I'll see why this is necessary later, but this seems odd since it looks like it would
create a CreateTableAsSelectStmt, only to be passed as an arg to CreateTableAsSelectStmt.

File fe/src/main/java/org/apache/impala/analysis/CreateTableStmt.java:

PS1, Line 68:   public static CreateTableStmt CreateTableAsSelectStmt(TableDef tableDef) {
            :     CreateTableStmt stmt = new CreateTableStmt(tableDef);
            :     stmt.createAsSelect_ = true;
            :     return stmt;
            :   }
yeah, per my comment in sql-parser this seems odd to have this parameter on CreateTableStmt
while the CreateTableAsSelectStmt consumes this.

why can't you just set isExternal = true in the TableDef? Maybe I'm missing something?
