[jira] Created: (HBASE-3598) Broken formatting in LRU stats output
Broken formatting in LRU stats output
-------------------------------------
Key: HBASE-3598
URL: https://issues.apache.org/jira/browse/HBASE-3598
Project: HBase
Issue Type: Bug
Affects Versions: 0.90.1
Reporter: Todd Lipcon
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.

[jira] [Updated] (HBASE-3598) Broken formatting in LRU stats output
Posted by "Erik Onnen (JIRA)" <ji...@apache.org>.
[ https://issues.apache.org/jira/browse/HBASE-3598?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Erik Onnen updated HBASE-3598:
------------------------------
Fix Version/s: 0.92.0
Status: Patch Available (was: Open)
Should fix the logging output but I wonder if other consumers of getHitRatio and getHitCachingRatio won't have the same issue and if those shouldn't also return 0 instead of NaN.

Oh, appears to be when trying to format NaN as a percentage.

Applied to TRUNK. Thanks for patch Erik. For other consumers of NaN in the system, lets open new issues for them as we turn the up.
