Subject [Impala-ASF-CR] Release note updates for Impala 2.8
Date Sat, 04 Feb 2017 00:05:15 GMT
John Russell has posted comments on this change.

Change subject: Release note updates for Impala 2.8

Patch Set 7:


Addressed all comments. Dealt with some gerrit glitches (had to squash 2 commits that appeared
to both have the same change ID, one of which had gone into the wrong private branch.)
File docs/shared/impala_common.xml:

Not adding, this one was already here AFAIK.

I am occasionally held up for some time resolving a merge conflict or otherwise dealing with
gerrit glitches.

OK. I had an item mentioning the uppercasing under 2.7. That might have been an assumption
on my part because of the timing of when this came to light. I'll remove it under 2.7 as well.
File docs/topics/impala_new_features.xml:

PS3, Line 53: / CDH 5.10.x
> I do not see a response to his yet.
Done. I am doing a bunch of replacements with substitution variables in these titles, although
not 100% of the titles in this file. Back in the Impala 1.3 / 1.2 days, there was some discontinuity
around the release numbering (e.g. new features going out in .1 maintenance releases) and
I'll leave that cleanup for a subsequent CR.

Holding off on making any big changes to line length in individual CRs, saving that for a
global change later.

Done. I'll do some follow-on work to link to the specific JIRAs rather than just summarizing
each improvement. (I'll probably save that for a follow-on CR.)

Done. Puzzling because I'm avoiding reformatting existing lines. Trailing spaces are usually
removed by my pre-commit hook but I haven't tested that hook with the ASF repo.
