Description

Current in HRegion.internalPut

    this.updatesLock.readLock().lock();
    checkFamilies(familyMap.keySet());
    checkTimestamps(familyMap, now);
    updateKVTimestamps(familyMap.values(), byteNow);
    .....
    this.updatesLock.readLock().unlock();

We can change it to

    checkFamilies(familyMap.keySet());
    checkTimestamps(familyMap, now);
    updateKVTimestamps(familyMap.values(), byteNow);
    this.updatesLock.readLock().lock();
    .....
    this.updatesLock.readLock().unlock();
