Anoop Sam John commented on HBASE-16696:
----------------------------------------

Is this a flaky test from long time?
{code}
ScanThread[] scanThreads = initiateScan(table, true);
      Thread.sleep(200);
      Iterator<CachedBlock> iterator = cache.iterator();
      boolean usedBlocksFound = false;
      int refCount = 0;
      int noOfBlocksWithRef = 0;
      while (iterator.hasNext()) {
        CachedBlock next = iterator.next();
        BlockCacheKey cacheKey = new BlockCacheKey(next.getFilename(), next.getOffset());
        if (cache instanceof BucketCache) {
          refCount = ((BucketCache) cache).getRefCount(cacheKey);
        } else if (cache instanceof CombinedBlockCache) {
          refCount = ((CombinedBlockCache) cache).getRefCount(cacheKey);
        } else {
          continue;
        }
        if (refCount != 0) {
          // Blocks will be with count 3
          System.out.println("The refCount is " + refCount);
          assertEquals(NO_OF_THREADS, refCount);
{code}
3 scanner threads were started and we sleep for 200 msec and then assert that blocks have 3 as ref count.  What is a scan got completed in btw?  Then that ref count dec would have happened.   Ping [~ram_krish]
