Robert Joseph Evans commented on MAPREDUCE-3819:
------------------------------------------------
OK So the issue is that Tokens and Renewal of the tokens has been abstracted
away so much that the RM has no direct reference to HDFS at all. The
DFSClient.Renewer is loaded using a ServiceLoader and there is no reference to
HdfsConfiguration from DFSClient.Renewer. The best I can think of is to create
a static method in HdfsConfiguration that is a noop, but documents what is
happening, and have it called from DFSClient.Renewer. Without the method we
run the risk of having someone clean up code that is not needed and have these
things go away.
