Tsz Wo (Nicholas), SZE commented on HDFS-1923:
----------------------------------------------
In some other cases, it failed with
{noformat}
Failed to add a datanode: nodes.length != original.length + 1,
nodes=[127.0.0.1:51603], original=[127.0.0.1:51603]
java.io.IOException: Failed to add a datanode: nodes.length != original.length
+ 1, nodes=[127.0.0.1:51603], original=[127.0.0.1:51603]

org.apache.hadoop.hdfs.DFSOutputStream$DataStreamer.findNewDatanode(DFSOutputStream.java:768)
{noformat}
It seems that there are not enough datanodes. I will check this.
