Subject [jira] [Commented] (HBASE-16408) Handle On heap BucketCache size when HeapMemoryManager tunes memory
Date Fri, 16 Sep 2016 07:11:20 GMT

    [ https://issues.apache.org/jira/browse/HBASE-16408?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15495603#comment-15495603

Anoop Sam John commented on HBASE-16408:
----------------------------------------

As of now there is no problem (I was wrong).. Even if BucketCache is onheap, we dont consider
that size at all in size calc for HeapMemory tuner.    Now we have optimized off heap read
so am wondering why we need on heap version of bucket cache.   File and off heap mode is enough?
 Do some one really using BucketCache on heap?  Off heap will perform equally or even better
now.  [~stack] how abt removing on heap Bucket cache mode?
