Description

I've seen this a few times - the output for LRU stats ends up with some invalid characters in it:

11/03/03 14:36:06 DEBUG hfile.LruBlockCache: LRU Stats: total=1.49 MB, free=180.56 MB, max=182.05 MB, blocks=0, accesses=0, hits=0, hitRatio=�%, cachingAccesses=0, cachingHits=0, cachingHitsRatio=�%, evictions=0, evicted=0, evictedPerRun=NaN

Note the messed up "hitRatio" and "cachingHitsRatio". I can't figure out how to reproduce, though.
