> The test is wrongly finding out the datanode to be corrupted from the block
> locations. Instead of finding out a datanode which is used in the block
> locations it is simply getting a datanode from the cluster, which may not be
> a datanode present in the block locations.
> {code}
> byte[] indices = lastBlock.getBlockIndices();
> //corrupt the first block
> DataNode toCorruptDn = cluster.getDataNodes().get(indices[0]);
> {code}
> For example, datanodes in the cluster.getDataNodes() array indexed like,
> 0->Dn1, 1->Dn2, 2->Dn3, 3->Dn4, 4->Dn5, 5->Dn6, 6->Dn7, 7->Dn8, 8->Dn9,
> 9->Dn10
> Assume the datanodes which are part of block location is => Dn2, Dn3, Dn4,
> Dn5, Dn6, Dn7, Dn8, Dn9, Dn10. Now, in the failed scenario, it is getting the
> corrupted datanode as cluster.getDataNodes().get(0) which will be Dn1 and
> corruption of this datanode will not result in ECWork and is failing the
> tests.
> Ideally, the test should find a datanode from the block locations and corrupt
> it, that will trigger ECWork.
