Subject [jira] [Created] (HBASE-11938) Unify cache configuration
Date Wed, 10 Sep 2014 22:44:34 GMT
Nick Dimiduk created HBASE-11938:

             Summary: Unify cache configuration
                 Key: HBASE-11938
                 URL: https://issues.apache.org/jira/browse/HBASE-11938
             Project: HBase
          Issue Type: Improvement
          Components: regionserver
            Reporter: Nick Dimiduk
            Priority: Minor

As pointed out in a [comment|https://issues.apache.org/jira/browse/HBASE-11331?focusedCommentId=14128811&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-14128811]
on HBASE-11331, our configuration keys for the blockcache are all over the place.

There's not a lot of consistency around cache configurations. We also have:
 - hbase.rs.cacheblocksonwrite
 - hfile.block.index.cacheonwrite
 - hfile.block.bloom.cacheonwrite
 - hbase.rs.evictblocksonclose
 - hbase.bucketcache.*
 - hbase.rs.prefetchblocksonopen
 - hbase.offheapcache.minblocksize

We should rename them to a consistent scheme.
