Description

In oracle and postgres, rpad and lpad functions defaults to spaces when str2 is not specified - rpad(str1, length [, str2]). For example in oracle:

SQL> select rpad(name,20) from voter where voter_id=10;

RPAD(NAME,20)
--------------------
tom underhill

SQL> select lpad(name,20) from voter where voter_id=10;

LPAD(NAME,20)
--------------------
tom underhill

In drill, the queries fail because the str2 parameter is required:

0: jdbc:drill:schema=dfs> relect lpad(name, 20) from voter where voter_id=10;
Query failed: org.apache.drill.exec.rpc.RpcException: Remote failure while running query.[error_id: "dde5cf1c-1d05-46c4-902a-c4bd6621c065"
