Benedict commented on CASSANDRA-8750:
-------------------------------------
This was broken from the get go for compressed files, which we don't cover by
default in our unit tests. The fix was very simple, but I've also made the
SSTableRewriterTest work for compressed files. Patch available
[here|github.com/belliottsmith/cassandra/tree/8750-fix]
> Ensure SSTableReader.last corresponds exactly with the file end

> Project: Cassandra
> Issue Type: Improvement
> Components: Core
> Reporter: Benedict

> Priority: Minor
> Fix For: 2.1.4

> Following on from CASSANDRA-8744, CASSANDRA-8749 and CASSANDRA-8747, this
> patch attempts to make the whole opening early of compaction results more
> robust and with more clearly understood behaviour. The improvements of
> CASSANDRA-8747 permit is to easily align the last key with a summary
> boundary, and an index and data file end position. This patch modifies
> SegmentedFile to permit the provision of an explicit length, which is then
> provided to any readers, which enforce it, ensuring no code may accidentally
> see an end inconsistent with the one advertised.
