Subject [jira] Commented: (HBASE-1615) HBASE-1597 introduced a bug when compacting after a split
Date Tue, 07 Jul 2009 02:25:14 GMT

    [ https://issues.apache.org/jira/browse/HBASE-1615?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12727881#action_12727881
] 

Jonathan Gray commented on HBASE-1615:
--------------------------------------

Issue is, we have a local readBlock in CompactionReader but that the delegate Reader does
not use our cacheBlock method.

I think this might be much easier if we just upgrade "block should be cached" to a passed
boolean to HFile Reader and Scanner instantation, rather than all this subclassing, delegating,
and such.

> The way HBASE-1597 instantiated the CompactionReader ignored whether the Reader it came
from was a half reader or not.
> Need to reimplement CompactionReader.
