[jira] [Commented] (HBASE-4017) BlockCache interface should be truly modular

    [ https://issues.apache.org/jira/browse/HBASE-4017?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13053439#comment-13053439 ] 

Jonathan Gray commented on HBASE-4017:
--------------------------------------

+1

FYI, in the upcoming HFile v2 stuff, there is a change in the block cache interface so that instead of ByteBuffer it takes HeapSize (so basically, any heap-size-aware structure).

> Currently, the if the BlockCache that used isn't an LruBlockCache, somewhere in metrics will try to cast it to an LruBlockCache and cause an exception. The code should be modular enough to allow for the use of different block caches without throwing an exception.
