Eli Collins commented on HDFS-4047:
-----------------------------------

@Todd, roger.  @Yanbo, would you like to post a patch that (unlike mine) is just cleanup and
preserves the current behavior of retrying on all exceptions?

> BPServiceActor#run and offerService booth have while shouldRun loops. We only need the
outer one, ie we can hoist the info log from offerService out to run and remove the while
loop.
