> TestAddOverReplicatedStripedBlocks#testProcessOverReplicatedAndCorruptStripedBlock occasionally appear failed.
> Failed code Line is 
> {code:java}
> // verify that all internal blocks exists except b0
> // the redundant internal blocks will not be deleted before the corrupted
> // block gets reconstructed. but since we set
> // DFS_NAMENODE_REPLICATION_MAX_STREAMS_KEY to 0, the reconstruction will
> // not happen
> lbs = cluster.getNameNodeRpc().getBlockLocations(filePath.toString(), 0,
>  fileLen);
> bg = (LocatedStripedBlock) (lbs.get(0)); 
> assertEquals(groupSize + 1, bg.getBlockIndices().length); //here not equals. {code}
> From the perspective of normal logic, the internal blocks that need to be obtained are 10, 8 live and 2 redundant internal blocks, 
> but due to the processing logic that occasionally triggers invalidate to remove redundant internal block, 
> the final obtained internal blocks value does not meet expectations.
> So need avoid the redundant internal blocks will be deleted.
