Benoy Antony commented on HDFS-4794:
------------------------------------
Sorry , I didn't see this comment.
The code structure is different and we need a much bigger change to fix this
using the Hadoop 2 approach. Its not a simple backport.
I am not sure about the use case of StreamFile and whether the same change
needs to be made there. Does it fall into the same category as the file system
browsing by webui ?
If so, I can make the same change and resubmit the patch.
I checked all other places in the code where
DataNode.getDataNode().getNameNodeAddr() is invoked and none of them require
this change.
It will be great to get this committed as this is bug for sure.
