Subject [jira] Resolved: (HBASE-1486) BLOCKCACHE always on even when disabled
Date Mon, 08 Jun 2009 01:50:07 GMT

     [ https://issues.apache.org/jira/browse/HBASE-1486?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

stack resolved HBASE-1486.
--------------------------

    Resolution: Fixed

Committed.  Thanks for the patch Lars.

In 0.19.x, we had block cache on for catalog tables as default (off for historian).  We wanted
to have block cache on for all tables by default for same reasons as I see being put forward
up on #hbase but in 0.19, block cache could cause us to OOME so we were selective -- the catalog
tables only.

I added note that migration needs to enable block cache on tables or at least recommend that
old tables have it manually enabled.
