Subject [jira] [Commented] (HBASE-6312) Make BlockCache eviction thresholds configurable
Date Sun, 08 Jul 2012 04:12:35 GMT

    [ https://issues.apache.org/jira/browse/HBASE-6312?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13408844#comment-13408844

Jie Huang commented on HBASE-6312:
----------------------------------

I agree to modify those 2 configuration items here. Meanwhile, another point which Jason states
here is how to make the customer understand the relationship between hfile.block.cache.size
and actual cached size. The configurable items somehow can make them aware of the thresholds
existing, and what the expected result is. Otherwise, they need to read the source code or
ask in MailList.

> Some of our customers found that tuning the BlockCache eviction thresholds made test
results different in their test environment. However, those thresholds are not configurable
in the current implementation. The only way to change those values is to re-compile the HBase
source code. We wonder if it is possible to make them configurable.
