--------------------------------------

             Summary: Replacing the type of paths from String to Hadoop Path
                 Key: DRILL-5603
                 URL: https://issues.apache.org/jira/browse/DRILL-5603
             Project: Apache Drill
          Issue Type: Improvement
    Affects Versions: 1.10.0
            Reporter: Vitalii Diravka
             Fix For: 1.11.0


String paths are used in the different places of the Drill code:
FileSelection, Metadata, ParquetGroupScan, ReadEntryWithPath, FileWork, FormatSelection, FormatPlugin,
PartitionLocation and so on.
Code with paths as strings is hard to test and maintain. And there are a lot of String to
Path conversions and vice versa.

The aim of this jira to replace String paths with Hadoop Path. The job of the Path class is
do properly implement file path operations, just as the job of the older File and newer Path
classes in Java is to handle OS paths.

For the serialized structures a custom JsonSerializer<Path> and JsonDeserializer<Path>
can be implemented.
