> Erroneous detection of corrupted file when namenode fails to allocate any

> Key: HADOOP-2275

> Project: Hadoop
> Issue Type: Bug

> Affects Versions: 0.15.0

>
> It can so happen that the namenode allocated a block for a file and then
> fails to allocate any datanode for this block. The namenode delivers an
> exception to the client. The client retries. But the block remains associated
> with the file (until lease expiration). This causes all client retries to
> fail.
> An fsck (before the lease expires) reports this block as a missing block.
