Description

Delegation token renewal in JobTracker uses https if there is a failure in creation of DistributedFileSystem. This handles the case when server is using a different version. With the changes in HADOOP-7227 the, creation of DistributedFileSystem will not fail because the creation of file system object doesn't make a connection or an rpc call. Therefore, the switchover to https should happen after an attempt to renew over rpc fails.
