> the getCorruptFiles() api is based on blocks that are in the queue of under-replicated blocks. However, this queue might be outdated and report blocks that are safe, specially during restarts when block reports might get delayed.
> getCorruptFiles() should double check if the block is really corrupted based on blocksMap before reporting it.
