Description

hbase-server/src/main/java/org/apache/hadoop/hbase/regionserver/compactions/SortedCompactionPolicy.java

public long getNextMajorCompactTime(Collection<HStoreFile> filesToCompact) {
{
    // default = 24hrs
   long period = comConf.getMajorCompactionPeriod();
    ...
    // default = 20% = +/- 4.8 hrs
    double jitterPct = comConf.getMajorCompactionJitter();
    ...
}

If I get it correctly, currently, default major compaction period is 7 days，and jitter is 0.5, so 3.5 days.
We could either remove those comments, or add {@link} to link to the default value definitions.
