Subject Re: Re: HDFS file is listable but not queryable (object not found)
Date Thu, 23 Jul 2020 15:58:00 GMT

apache drill> SELECT * FROM hdfs.`/tmp/employee.json`;
Error: VALIDATION ERROR: From line 1, column 15 to line 1, column 18: Object '/tmp/employee.json'
not found within 'hdfs'

 However, it might also be that Drill isn't finding the file for some reason.
