Allen Wittenauer commented on HDFS-1634:
----------------------------------------
In fact, there is a ton of TODO:FEDERATION comments all over.
.. and then there is this beauty:
{code}
+ for (BPOfferService bpos : dn.nameNodeThreads) {
+ LOG.info("reg: bpid=" + "; name=" + bpos.bpRegistration.name
+ + "; sid=" + bpos.bpRegistration.storageID + "; nna=" +
bpos.nn_addr);
+ }
{code}
LOG.info? Seriously? What is someone who isn't knee deep in the code supposed
to get out of that log message?

Fix this mess.
