[jira] [Created] (ACCUMULO-4520) Utilize Java 8 in RFile

Michael Miller created ACCUMULO-4520:
----------------------------------------

             Summary: Utilize Java 8 in RFile
                 Key: ACCUMULO-4520
                 URL: https://issues.apache.org/jira/browse/ACCUMULO-4520
             Project: Accumulo
          Issue Type: Improvement
          Components: core
    Affects Versions: 2.0.0
            Reporter: Michael Miller
            Priority: Minor
             Fix For: 2.0.0


There are a few places in o.a.a.core.file.rfile.RFile where Java 8 functional program could improve readability. There is some potential for performance improvement as well.

One example of an improvement would be to change the 3 LocalityGroupReader arrays (currentReaders, readers and sampleReaders) in the RFile.Reader class to ArrayLists. This would allow use of the forEach in stream package.
