Subject [jira] Commented: (HBASE-1127) OOME running randomRead PE
Date Fri, 16 Jan 2009 01:36:59 GMT

    [ https://issues.apache.org/jira/browse/HBASE-1127?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12664357#action_12664357
] 

Jean-Daniel Cryans commented on HBASE-1127:
-------------------------------------------

bq. Given that we're up against the RC, I am currently thinking that I'll revert to having
blockcache on by default and instead let users choose it explicitly (with the checker running
every second). I'll leave it on in catalog tables so meta content has block cache on.

> Blockcache is misbehaving on TRUNK.  Something is broke.  We OOME about 20% into the
randomRead test.  Looking at heap, its all soft references.  Instrumenting the referencequeue,
we're never clearing full gc'ing.  Something is off.
