[jira] [Commented] (HBASE-15386) PREFETCH_BLOCKS_ON_OPEN in HColumnDescriptor is ignored

    [ https://issues.apache.org/jira/browse/HBASE-15386?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15179065#comment-15179065 ] 

Andrew Purtell commented on HBASE-15386:
----------------------------------------

I vote for hook it up again unless we want to purge the whole prefetch experiment on account of it not being used or not being useful.

> We use the global flag hbase.rs.prefetchblocksonopen only and ignore the HCD setting.
> Purge from HCD or hook it up again (it probably worked once).
> Thanks to Daniel Pol for finding this one. Let me fix.
