[jira] [Created] (DRILL-7834) Add Utility Functions for Compressed Files

Charles Givre created DRILL-7834:
------------------------------------

             Summary: Add Utility Functions for Compressed Files
                 Key: DRILL-7834
                 URL: https://issues.apache.org/jira/browse/DRILL-7834
             Project: Apache Drill
          Issue Type: Improvement
          Components: Storage - Text &amp; CSV
    Affects Versions: 1.17.0
            Reporter: Charles Givre
            Assignee: Charles Givre
             Fix For: 1.19.0


Some format plugins that use third party parsers throw errors when they receive compressed input streams from Drill.  This PR proposes to introduce three utility functions to the DrillFileSystem:
# isCompressed(<path>):  Returns true/false whether the input file is compressed
# getCodec(<path>):  This method returns the codec of the file if any
# openDecompressedInputStream(<path>):  Returns an InputStream that should be readable by parsers that read raw bytes.  This method converts the original InputStream to a byte[] first, then returns that via a ByteArrayInputStream.
