> Key: HBASE-20208
> URL: https://issues.apache.org/jira/browse/HBASE-20208
> Project: HBase
> Issue Type: Improvement
> Affects Versions: 2.0.0
> Reporter: BELUGA BEHR
> Assignee: BELUGA BEHR
> Priority: Minor
> Attachments: 20208.1.patch, HBASE-20208.1.patch
>
>
> # Fix checkstyle warnings
> # Use re-usable libraries where possible
> # Improve Map Access
> What got my attention on this class was:
> {code}
> for (Map.Entry<byte[], Long> e : sequenceids.entrySet()) {
> long oldestFlushing = Long.MAX_VALUE;
> long oldestUnflushed = Long.MAX_VALUE;
> if (flushing != null && flushing.containsKey(e.getKey())) {
> oldestFlushing = flushing.get(e.getKey());
> }
> if (unflushed != null && unflushed.containsKey(e.getKey())) {
> oldestUnflushed = unflushed.get(e.getKey());
> }
> long min = Math.min(oldestFlushing, oldestUnflushed);
> if (min <= e.getValue()) {
> return false;
> }
> {code}
> Here, the two maps are calling _containsKey_ and then _get_. It is also
> calling {{e.getKey()}} repeatedly.
> I propose changing this so that {{e.getKey()}} is only called once and
> instead of looking up an entry with _containsKey_ and then a _get_, simply
> use _get_ once and check for a 'null' value to check for existence. It saves
> two trips through the Map Collection on each loop.
