    [SPARK-19599][SS]Clean up HDFSMetadataLog for Hadoop 2.6+

    ## What changes were proposed in this pull request?
    
    SPARK-19464 removed support for Hadoop 2.5 and earlier, so we can do some cleanup for HDFSMetadataLog.
    
    This PR includes the following changes:
    - Remove the workaround codes for HADOOP-10622.
    - Remove unnecessary `writer: (T, OutputStream) => Unit` and just call `serialize` directly.
    
    ## How was this patch tested?
    
    Jenkins
