Harsh J resolved HDFS-10.
-------------------------
Resolution: Won't Fix
These things help ops determine HDFS activity. If you do not wish to see them
ever, you may turn up the logging to a WARN or higher level. Its INFO by
default.
Resolving as Won't Fix, as these things are useful and yet not too much info to
be DEBUG-only.

> I notice that in FSNamesystem.java, about 10 lines above this line is logged,
> there is a comment:
> //
> // Move the block-replication into a "pending" state.
> // The reason we use 'pending' is so we can retry
> // replications that fail after an appropriate amount of time.
> // (REMIND - mjc - this timer is not yet implemented.)
