patch by Richard Low and jbellis for CASSANDRA-2039
> LazilyCompactedRow doesn't add CFInfo to digest
> -----------------------------------------------
>
> Key: CASSANDRA-2039
> URL: https://issues.apache.org/jira/browse/CASSANDRA-2039
> Project: Cassandra
> Issue Type: Bug
> Components: Core
> Affects Versions: 0.7.0
> Reporter: Richard Low
> Priority: Minor
> Fix For: 0.8
>
> Attachments: trunk-2038-LazilyCompactedRowTest.txt,
> trunk-2038-v2.txt, trunk-2038.txt

>
> LazilyCompactedRow.update doesn't add the CFInfo or columnCount to the
> digest, so the hash value in the Merkle tree does not include this data.
> However, PrecompactedRow does include this. Two consequences of this are:
> * Row-level tombstones are not compared when using LazilyCompactedRow so
> could remain inconsistent
> * LazilyCompactedRow and PrecompactedRow produce different hashes of the same
> row, so if two nodes have differing in_memory_compaction_limit_in_mb values,
> rows of size in between the two limits will have different hashes so will
> always be repaired even when they are the same.
