Subject [jira] [Commented] (HBASE-4838) Port 2856 (TestAcidGuarantee is failing) to 0.92
Date Sat, 26 Nov 2011 00:02:40 GMT

    [ https://issues.apache.org/jira/browse/HBASE-4838?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13157345#comment-13157345

Lars Hofhansl commented on HBASE-4838:

Finally found the problem!!
It was indeed a problem in HalfStoreFileReader (as Todd and Stack have suggested all along).
HalfStoreFileReader did not have a getScanner(final boolean cacheBlocks, final boolean pread,
final boolean isCompaction) method, and hence the super method was called returning a normal

bq. Reference.java and HalfStoreFileReader.java are identical between 0.92 and trunk

I don't know what I was comparing here (must have been late in the night), but they are different
and that difference was exactly the problem. Could have saved myself about 16 hours of debugging.

> Moving back port into a separate issue (as suggested by JonH), because this not trivial.
