Status: Patch Available (was: Open)
> Improve CompactSelection
> ------------------------
>
> Key: HBASE-7437
> URL: https://issues.apache.org/jira/browse/HBASE-7437
> Project: HBase
> Issue Type: Improvement
> Components: Compaction
> Reporter: Hiroshi Ikeda
> Priority: Minor
> Attachments: HBASE-7437.patch
>
>
> 1. Using AtomicLong makes CompactSelection simple and improve its performance.
> 2. There are unused fields and methods.
> 3. The fields should be private.
> 4. Assertion in the method finishRequest seems wrong:
> {code}
> public void finishRequest() {
> if (isOffPeakCompaction) {
> long newValueToLog = -1;
> synchronized(compactionCountLock) {
> assert !isOffPeakCompaction : "Double-counting off-peak count for compaction";
> {code}
> The above assertion seems almost always false.
