[jira] [Commented] (HBASE-17047) Add an API to get HBase connection cache statistics

["Weiqing Yang (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HBASE-17047?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15649860#comment-15649860 ] 

Weiqing Yang commented on HBASE-17047:
--------------------------------------

Sorry for the misleading title/description. Our client has asked us to log information about the cache, but we’ve decide not to do so. It’s an API that gives statistics information of the cache (like you suggested). The refcount has nothing to do with this patch, but its decrement is here: https://github.com/apache/hbase/blob/master/hbase-spark/src/main/scala/org/apache/hadoop/hbase/spark/HBaseConnectionCache.scala#L131
