> Project: Apache Drill
> Issue Type: Bug
> Components: Storage - Other
> Reporter: Daniel Barclay (Drill)
> Assignee: Hanifi Gunes
> Fix For: 1.4.0

>
> {{BasicFormatMatcher.isReadable(...)}} calls {{getFirstPath(...)}} without
> checking that there is at least one path. This can cause an
> IndexOutOfBoundsException.
> To reproduce, create an empty directory {{/tmp/CaseInsensitiveColumnNames}}
> and run
> {{exec/java-exec/src/test/java/org/apache/drill/TestExampleQueries.java}}.
