Subject [jira] [Updated] (HBASE-15386) PREFETCH_BLOCKS_ON_OPEN in HColumnDescriptor is ignored
Date Wed, 20 Apr 2016 16:52:25 GMT

     [ https://issues.apache.org/jira/browse/HBASE-15386?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

stack updated HBASE-15386:
--------------------------
       Resolution: Fixed
    Fix Version/s: 1.2.2
                   1.4.0
                   1.3.0
                   2.0.0
     Release Note: 
This was a non-issue. The PREFETCH_... flag actually works. While here though made the following
additions.

Changes the prefetch TRACE-level loggings to include the word 'Prefetch' in them so you know
what they are about.

Changes the cryptic logging of the CacheConfig#toString to have some preamble saying why and
what column family is responsible (helps figure what is going on)

Add test that verifies setting flag on HColumnDescriptor actually works.
           Status: Resolved  (was: Patch Available)

> 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.
