Description

Currently, DistCpV1 is using deprecated methods and having wrong javadocs. We should fix them.

1. DistCpV1.copy doesn't have dstpath, but javadoc has it.

    /**
     * Copy a file to a destination.
     * @param srcstat src path and metadata
     * @param dstpath dst path

2. Removing deprecated methods.

         SequenceFile.Writer dir_writer = SequenceFile.createWriter(jobfs, jobConf, dstdirlist, Text.class, FilePair.class, SequenceFile.CompressionType.NONE);

        basedir = args.basedir.makeQualified(basefs);
