I have performing some select commands tests of drill.

Test case 1:  user is mysql table, it is error. 
0: jdbc:drill:zk=SC-1:6181,SC-2:6181,PL-3:618> select count(1) from mysql.user;
Error: PARSE ERROR: Encountered ". user" at line 1, column 32.
Was expecting one of:
    <EOF>
    "ORDER" ...
while parsing SQL query:
select count(1) from mysql.user
                               ^
[Error Id: 484485a4-6e0a-45cd-892a-099236319109 on SC-1:31010] (state=,code=0)

Test case 2:  user is mysql table, i add ` on user table. it is right. 
0: jdbc:drill:zk=SC-1:6181,SC-2:6181,PL-3:618> select count(1) from mysql.`user`;
