[jira] [Commented] (HADOOP-9576) Make NetUtils.wrapException throw
EOFException instead of wrapping it as IOException

Steve Loughran commented on HADOOP-9576:
----------------------------------------
I've seen this, and yes, it should be handled and marked as "connection torn town"

We'll need a corresponding Wiki page along with the code patch

> In case of EOFException, NetUtils is now wrapping it as IOException, we may want to throw EOFException as it is, since EOFException can happen when connection is lost in the middle, the client may want to explicitly handle such exception
