Subject [jira] [Commented] (HBASE-10531) Revisit how the key byte[] is passed to HFileScanner.seekTo and reseekTo
Date Fri, 14 Mar 2014 12:54:43 GMT

    [ https://issues.apache.org/jira/browse/HBASE-10531?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13934954#comment-13934954
] 

ramkrishna.s.vasudevan commented on HBASE-10531:
------------------------------------------------

I think some problem with the RB.  Getting this error
'The file "hbase-common/src/main/java/org/apache/hadoop/hbase/CellComparator.java" (revision
18d54f8) was not found in the repository'.
HFilePerformanceEvaluation and TestHFilePerformance are still using KeyValue.RawBytesComparator.
Can we change that?  
Will prepare a micro benchmark report in the beginning of next week.

> Currently the byte[] key passed to HFileScanner.seekTo and HFileScanner.reseekTo, is
a combination of row, cf, qual, type and ts.  And the caller forms this by using kv.getBuffer,
which is actually deprecated.  So see how this can be achieved considering kv.getBuffer is
removed.
