> 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.
