>
> In a scenario where the corrupt replica is on a failed storage, before it is
> taken out of blocksMap, there is a race which causes the creation of
> LocatedBlock on a {{machines}} array element that is not populated.
> Following is the root cause,
> {code}
> final int numCorruptNodes = countNodes(blk).corruptReplicas();
> {code}
> countNodes only looks at nodes with storage state as NORMAL, which in the
> case where corrupt replica is on failed storage will amount to
> numCorruptNodes being zero.
> {code}
> final int numNodes = blocksMap.numNodes(blk);
> {code}
> However, numNodes will count all nodes/storages irrespective of the state of
> the storage. Therefore numMachines will include such (failed) nodes. The
> assert would fail only if the system is enabled to catch Assertion errors,
> otherwise it goes ahead and tries to create LocatedBlock object for that is
> not put in the {{machines}} array.
> Here is the stack trace:
> {code}
