Apache drill validation error, table not found

[Bo Qiang]

I have been trying to use Apache drill to query data in s3 buckets. Inside
of Drill Explorer, I met the following errors:

    ERROR [HY000] [MapR][Drill] (1040) Drill failed to execute the query:
SELECT * FROM `s3`.`default`.`./data/part-r-001` LIMIT 100
    [30034]Query execution error. Details:[
    VALIDATION ERROR: From line 1, column 15 to line 1, column 18: Table
's3.default../data/part-r-001' not found

    SQL Query null

       at DrillExplorer.DROdbcProvider.GetStatmentColumns(String in_query)

The part-r-001 file are of ORC format.

Is there anything fix? Thanks a lot!
