Improvements
[ https://issues.apache.org/jira/browse/HBASE-19675?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16307435#comment-16307435 ]
Chia-Ping Tsai commented on HBASE-19675:
----------------------------------------
{code}
- if (files == null || files.isEmpty()) {
- return new ArrayList<>();
+ if (CollectionUtils.isEmpty(files)) {
+ return Collections.emptyList();
}
{code}
Could we file a jira to address such a issue?There are 2xx same pattern in our hbase.

>
> * 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}
