> * Remove logging code guards in favor of slf4j parameters
> * Use {{CollectionsUtils.isEmpty()}} consistently
> * Small check-style fixes
> * Remove flow control logic from {{trace}} statement {code}          if (LOG.isTraceEnabled())
{
>             LOG.trace("No compacted files to archive");
>             return;
>           }{code}
> * Replace two calls to the same getter to ensure that the value doesn't change between
calls {code}      if (getCompactedFiles() != null) {
>         for (HStoreFile file : getCompactedFiles()) {
>           name2File.put(file.getFileInfo().getActiveFileName(), file);
>         }
>       }{code}
> * Make 'inputFiles' a Set for fast calls to {{contains}} method instead {code}    //some
of the input files might already be deleted
>     List<HStoreFile> inputStoreFiles = new ArrayList<>(compactionInputs.size());
>     for (HStoreFile sf : this.getStorefiles()) {
>       if (inputFiles.contains(sf.getPath().getName())) {
>         inputStoreFiles.add(sf);
>       }
>     }{code}
