Although I couldn't reproduce the same problem for replication, this change may
fix it.

bq. As follow-on work, maybe we can create a utility function to check if a
block is corrupted/missing, considering this is widely used in
BlockManager/FSNamesystem.
I agree with you. It is also useful for others. For example, fsck counts some
low-redundancy metrics in its own way at the moment. It would be good if it
uses the same logic with {{LowRedundancyBlocks}}. I will consider it more and
create a new jira.

Thank you for your kind review, [~jingzhao]!
On second thought, we may not need to check it, like below. Because the blocks
in {{priorityQueues.get(QUEUE_WITH_CORRUPT_BLOCKS)}} is already took into
account various cases in {{LowRedundancyBlocks.getPriority}}. What do you think?
{code:title=FSNameSystem.listCorruptFileBlocks|borderStyle=solid}
while (blkIterator.hasNext()) {
BlockInfo blk = blkIterator.next();
final INodeFile inode = getBlockCollection(blk);
skip++;
if (inode != null) {
...
}
}

Thanks for working on this, [~tasanuma0829]! The patch looks good to me
overall. Some minors:
# I think we can rename "isCorrupt" to "isMissing". In the outer "while" loop,
we're scanning all the blocks with {{QUEUE_WITH_CORRUPT_BLOCKS}} priority, and
this "if" logic is to select missing blocks.
# We may also want to take into account the decommissioning/decommissioned
internal blocks for the check.
# As follow-on work, maybe we can create a utility function to check if a block
is corrupted/missing, considering this is widely used in
BlockManager/FSNamesystem.
# For the unit test, do you think we can use {{MiniDFSCluster#corruptReplica}}
to simplify the code?

We don't use ec in our builds but we see the error as shown in case_2.png but
we were not able to track down the root cause.
