Allen Wittenauer commented on HDFS-177:
---------------------------------------
We should verify that this is fixed.
I've seen an issue similar to this under 2.2.0 and I'm beginning to wonder if
it isn't the same problem.
> Error when 2 of 3 DataNodes are full: "Could only be replicated to 0 nodes,
> instead of 1"
> -----------------------------------------------------------------------------------------
>
> Key: HDFS-177
> URL: https://issues.apache.org/jira/browse/HDFS-177
> Project: Hadoop HDFS
> Issue Type: Bug
> Environment: * 3 machines, 2 of them with only 80GB of space, and 1
> with 1.5GB
> * Two clients are copying files all the time (one of them is the 1.5GB
> machine)
> * The replication is set on 2
> Reporter: Stas Oskin
>
> I let the space on 2 smaller machines to end, to test the behavior.
> Now, one of the clients (the one located on 1.5GB) works fine, and the other
> one - the external, unable to copy and displays the error + the exception
> below:
