> Key: HDFS-5428
> URL: https://issues.apache.org/jira/browse/HDFS-5428
> Project: Hadoop HDFS
> Issue Type: Bug
> Reporter: Vinay
>
> 1. allow snapshots under dir /foo
> 2. create a file /foo/test/bar and start writing to it
> 3. create a snapshot s1 under /foo after block is allocated and some data has
> been written to it
> 4. Delete the directory /foo/test
> 4. wait till checkpoint or do saveNameSpace
> 5. restart NN.
> NN enters to safemode.
> Analysis:
> Snapshot nodes loaded from fsimage are always complete and all blocks will be
> in COMPLETE state.
> So when the Datanode reports RBW blocks those will not be updated in
> blocksmap.
> Some of the FINALIZED blocks will be marked as corrupt due to length mismatch.
