This change modifies the output of the SHOW TABLE STATS and SHOW
PARTITIONS for Kudu tables.
- PARTITIONS: the #Row column has been removed
- TABLE STATS: instead of showing partition informations it returns a
resultset similar to HDFS table stats, #Rows, #Partitions, Size, Format
and Location
Example outputs can be seen in the doc changes.
Testing:
* kudu_stats.test is modified to verify the new result set
* kudu_partition_ddl.test is modified to verify the new partitions style
* Updated unit test with the new error message

Explain how doing COMPUTE INCREMENTAL STATS for the first time
starts over and discards any previous stats from COMPUTE STATS.
As a consequence, moved some wording and examples into
impala_common.xml so that content could be used in
multiple places. Also made a new subtopic on the "Partitioning"
page because I saw COMPUTE INCREMENTAL STATS wasn't mentioned
there.

The pre-commit hook that used to detect
and fix trailing spaces in doc XML files
seems to have bitrotted and some trailing
spaces made it into source files during the
initial upstream cleanup.

A number of 'CDH' by itself were turned into substitution
variables resolving to 'Apache Hadoop'.
Also fixed some stray instances of CDH version numbers.
In some cases, 'CDH' or 'CDH 5' by itself was superfluous and was
just removed.

Upgrade with details of latest syntax.
Fine-tune discussion of PK and other Kudu
notions.
The impala_kudu diff looks larger than actual changes
to the page, because subtopics got moved
around and promoted/demoted (which changes the
indentation). Best to review that page start-to-finish.
CREATE TABLE details for Impala + Kudu.
ALTER TABLE details for Impala + Kudu.
Unhide the Impala partitioning + Kudu topic.
Mainly a brief intro then a link to delegate
details to the main Kudu page, which already
has a partitioning subtopic.
Include changes to reserved words. Entirely
from Kudu integration work.
Add Kudu considerations for misc SQL statements.
Addressed Todd's and Dimitris's comments for certain files.
(Up to the beginning of the "Partitioning" section in
impala_kudu.xml.)
Added Kudu blurbs to data type topics:
- Some aren't supported.
- Others are supported but can't go in the primary key.
Added walkthrough of renaming internal/external tables.
Split out Kudu CREATE TABLE syntax from other file formats.
Correct info about CTAS for Kudu tables.
Add examples of basic Kudu, external Kudu, and Kudu CTAS.

COMPUTE STATS, and SHOW FILES.
Mixed in a little bit with new Kudu syntax for
ALTER TABLE. Didn't include all new Kudu info
in this CR, the better to minimize merge conflicts.
Added note about performance/scalability of IMPALA-1654.
Added new Known Issue item for IMPALA-4106 under Performance category.

For this change to land in master, the audience="hidden" code review
needs to be completed first. Otherwise, the doc build would still work
but the audience="hidden" content would be visible rather than hidden as
desired.
Some work happening in parallel might introduce additional instances of
audience="Cloudera". I suggest addressing those in a followup CR so this
global change can land quickly.
Since the changes apply across so many different files, but are so
narrow in scope, I suggest that the way to validate (check that no
extraneous changes were introduced accidentally) is to diff just the
changed lines:
git diff -U0 HEAD^ HEAD
In patch set 2, I updated other topics marked audience="Cloudera"
by CRs that were pushed in the meantime.
