----------------------------------
Assignee: (was: Jacques Nadeau)
> unknown suffixes .not_json and .json_not treated differently (multi-file case)
> ------------------------------------------------------------------------------

> Key: DRILL-3815
> URL: https://issues.apache.org/jira/browse/DRILL-3815
> Project: Apache Drill
> Issue Type: Bug
> Components: Storage - Other
> Reporter: Daniel Barclay (Drill)
>
> In scanning a directory subtree used as a table, unknown filename extensions
> seem to be treated differently depending on whether they're similar to known
> file extensions. The behavior suggests that Drill checks whether a file name
> _contains_ an extension's string rather than _ending_ with it.
> For example, given these subtrees with almost identical leaf file names:
> {noformat}
> $ find /tmp/testext_xx_json/
> /tmp/testext_xx_json/
> /tmp/testext_xx_json/voter2.not_json
> /tmp/testext_xx_json/voter1.json
> $ find /tmp/testext_json_xx/
> /tmp/testext_json_xx/
> /tmp/testext_json_xx/voter1.json
> /tmp/testext_json_xx/voter2.json_not
> $
> {noformat}
> the results of trying to use them as tables differs:
> {noformat}
> 0: jdbc:drill:zk=local> SELECT * FROM `dfs.tmp`.`testext_xx_json`;

> whether the extension contains an underscore character.)
