PS5, Line 40: - Flume 1.8+ requires Java 8 at runtime even though the Kudu 
Flume integration is Java 7
            :   compatible.  Flume 1.8 is the default dependency version as of 
Kudu 1.8.0.
this is a little confusing to me, since Kudu itself doesn't have Flume as a 
dependency.

Maybe we should say something like "The Flume sink released with Kudu 1.8.0 is 
now compiled to build against Flume 1.8 and will not function with earlier 
versions of Flume. Note that Flume 1.8 requires Java 8 or higher."

(I assume the "will not function" part is correct?)

That way it's clearer that this only affects people using Flume.

PS5, Line 43: - Hadoop 3.0+ requires Java 8 at runtime even though the Kudu 
Hadoop integration is Java 7
            :   compatible. Hadoop 3.1 is the default dependency version as of 
Kudu 1.8.0.
similar feedback here, I'm not sure what exactly this means. If I'm using 
Hadoop 2.x can I no longer use Kudu?

PS5, Line 53: deprecated
it appears that this configuration was removed, not deprecated. Deprecated 
means that it will still work but is being phased out, but I can't find it in 
the source anymore.

PS5, Line 58: deprecated
it seems these ones really are deprecated and not removed, right?


http://gerrit.cloudera.org:8080/#/c/11647/5/docs/release_notes.adoc@63
PS5, Line 63: == New features
I would argue that a lot of these new features are more "improvements". Can we 
move all of the smaller ones here into the improvements section and keep it to 
2-3 headline features?

PS5, Line 65: - A great deal of work went into providing examples that showcase 
Kudu client
style nit: i dont think the amount of work spent is relevant in the context of 
release notes. Better to just state the facts that we imported and improved a 
set of examples that were previously hosted in a separate repository on github

PS5, Line 101: Enable
nit: Enabled

PS5, Line 104: - Introduced rebalancer into the kudu CLI tool. The rebalancer 
can be used to redistribute
would say something like "a manual data rebalancer" instead of just 
"rebalancer" to be more specific. Is there documentation on this that can be 
linked to?


http://gerrit.cloudera.org:8080/#/c/11647/5/docs/release_notes.adoc@109
PS5, Line 109: - Replica selection in master honors placement policy. The way 
how the master places
             :   replicas of new tablets has changed. In essence (for details 
see
             :   https://s.apache.org/location-awareness-design), the placement 
policy is about:
             :
             : ** in case of N locations, N > 2, not placing the majority of 
replicas in one location;
             :
             : ** spreading replicas evenly among available locations;
             :
             : ** within a location, spreading replicas evenly among tablet 
servers.
is the placement policy work actually complete for this release? I thought it 
was still work-in-progress in terms of making the balancer, ksck, etc aware. I 
would suggest not including it here if it's not ready for primetime including 
docs and tool support.

PS5, Line 125:  15 minutes
15 minutes, really? isn't our server side scanner timeout one minute?

can this be expanded to indicate what kind of operations might be faster? iirc 
it improved scans where one endpoint was specified and the other was not or 
something?
