stack commented on HBASE-15713:
-------------------------------
[~mantonov] Just this patch. Relevant, non-controversial stuff from umbrella
has already gone in. This patch is mostly filled with doc and renamings around
HFileBlock serialization/deserialization ported from master with shutdowns of
the too-many methods in HFileBlock that are public. The 'fix' is stopping our
overwriting when saving the blocks to cache done for the fellows at hpe who are
doing perf analysis on our random reads (the overwrites is messing up their
cache accounting).

> Backport "HBASE-15477 Do not save 'next block header' when we cache
> hfileblocks"
> The backport involves removing support for hfile v1/hfileblockv1 support
> which was our default before 0.92. The backport patch also removes tests that
> depended on hfile v1, tests that were deprecated post 0.96 and to be removed
> (0.96 was the release that would only run if the whole cluster was hfiles >
> v1).
> [~mantonov] Ok to commit the above to 1.3? Thanks boss.
