-------------------------------------
Sorry, I did not notice that there is already a similar problem.

is already being resolved.

> _emphasized text_When I run a blockReport test with NNThroughputBenchmark,
> BlockReportStats.addBlocks() throws ArrayIndexOutOfBoundsException.
> digging the code:
> {code:java}
> for(DatanodeInfo dnInfo : loc.getLocations())
> { int dnIdx = dnInfo.getXferPort() - 1;
> datanodes[dnIdx].addBlock(loc.getBlock().getLocalBlock());{code}
>
> problem is here:array datanodes's length is determined by args as
> "-datanodes" or "-threads" ，but dnIdx = dnInfo.getXferPort() is a random port.
