Subject [jira] [Commented] (HBASE-8436) SeekBefore returns wrong result with PREFIX_TREE Encoding
Date Sun, 28 Apr 2013 01:15:13 GMT

    [ https://issues.apache.org/jira/browse/HBASE-8436?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13643852#comment-13643852
] 

Matt Corgan commented on HBASE-8436:
------------------------------------

I deleted that method and did import static org.junit.Assert.assertArrayEquals;

Now the last assertion fails, but I'm wondering if the Test is expecting the wrong row key.
 Chunhui, the last generated row key is batch0_row49, but because they are sorted before encoding,
the last key in the block should be batch0_row9.  Do you agree?

> In SeekBefore case, if we seek the key which is bigger than the last keyvalue
> PrefixTreeSeeker#seekToKeyInBlock will not seek correctly.
> Make the test case TestPrefixTreeEncoding#testSeekBeforeWithFixedData in the patch to
show this problem.
