      Description

      There are two potential bugs that make the NNThroughputBenchmark$BlockReportStats send empty block reports.

      1. In NNThroughputBenchmark$BlockReportStats#formBlockReport(), the blockReportList is always BlockListAsLongs.EMPTY. We should construct the block report list by encoding generated blocks in test.
      2. TinyDatanode#blocks is an empty ArrayList with initial capacity. In TinyDatanode#addBlock() first statement, the if(nrBlocks == blocks.size()) { will always be true. We should either fill the blocks with dummy report in TinyDatanode() constructor, or use initial capacity instead of blocks.size() in the above if statement (we should replace ArrayList#set with ArrayList#add as well).

          Thanks for the comment, Konstantin Shvachko.

          I totally agree with you that the code snippet above is better as the code change is small and simple. The v1 patch is to address this.

          It's worth to note that the Arrays.asList returns a java.util.Arrays.ArrayList object, which implements the List interface. The v1 patch changes the blocks type from ArrayList to List. Given that we don't add/delete items to/from this list, I think the List interface works just as fine as ArrayList.

          Yes indeed nrBlocks == blocks.size() always, because both are 0.
          Wouldn't it be easier to change the constructor of TinyDatanode

          -       this.blocks = new ArrayList<BlockReportReplica>(blockCapacity);
          +       this.blocks = Arrays.asList(new BlockReportReplica[blockCapacity]);
          

          Then the set logic will work as intended.

          The blockReportList part looks good.
