[jira] [Updated] (HBASE-11229) Change block cache percentage
metrics to be doubles rather than ints
[ https://issues.apache.org/jira/browse/HBASE-11229?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
stack updated HBASE-11229:
--------------------------
Attachment: 11229.txt
Try this. Also renames the metric in jmx from
- String BLOCK_CACHE_HIT_PERCENT = "blockCountHitPercent";
+ String BLOCK_CACHE_HIT_PERCENT = "blockCacheCountHitPercent";
... all other blockcache metrics have the 'blockCache' prefix but this one.

> See parent issue. Small changes in the hit percentage can have large implications, even when movement is inside a single percent: i.e. going from 99.11 to 99.87 percent. As is, percents are ints. Make them doubles.
