> There are a number of tickets (HDFS-10742, HDFS-10817, HDFS-10713, this subtask's story
HDFS-10475) which are adding/improving logging/metrics around the {{FSNamesystemLock}}. All
of this is done in {{FSNamesystem}} right now, which is polluting the namesystem with ThreadLocal
variables, timing counters, etc. which are only relevant to the lock itself and the number
of these increases as the logging/metrics become more sophisticated. It would be best to move
these all into FSNamesystemLock to keep the metrics/logging tied directly to the item of interest.
