Duo Zhang commented on HBASE-27919:
-----------------------------------

Confirm. This is a problem.

{code}
  public void takeSnapshot(SnapshotDescription snapshot) throws IOException {
    this.takingSnapshotLock.readLock().lock();
    try {
      takeSnapshotInternal(snapshot);
    } finally {
      this.takingSnapshotLock.readLock().unlock();
    }
  }

  public synchronized long takeSnapshot(SnapshotDescription snapshot, long 
nonceGroup, long nonce)
    throws IOException {
    this.takingSnapshotLock.readLock().lock();
    try {
      return submitSnapshotProcedure(snapshot, nonceGroup, nonce);
    } finally {
      this.takingSnapshotLock.readLock().unlock();
    }
  }
{code}

It is a bit strange that why one method is synchronized while another is not.

Let me dig more.

Thanks [~luoen].
