S3 Access errors

[Daniil Osipov]

I'm continuing exploration of accessing files on S3, and running into this
issue:
0: jdbc:drill:> *SELECT COUNT(1) FROM
s3n.root.`/dev/dan/cleaned_1210/clean.txt`;*
*Query failed: Query failed: Failure validating SQL.
org.eigenbase.util.EigenbaseContextException: From line 1, column 22 to
line 1, column 24: Table 's3n.root./dev/dan/cleaned_1210/clean.txt' not
found*

*Error: exception while executing query: Failure while executing query.
(state=,code=0)*

At the same time:
0: jdbc:drill:> *show files from s3n.`dev/dan/cleaned_1210/clean.txt`;*

*1 row selected (0.53 seconds)*

My storage config is below. Any suggestions on what could be wrong, or how
to debug this error?
