Subject [jira] [Updated] (HADOOP-12113) update test-patch branch to latest code

Allen Wittenauer updated HADOOP-12113:
--------------------------------------
    Release Note: 
The following changes have occurred vs. the release currently shipping with Hadoop:


MAJOR: 
* Documentation

A first pass at some documentation in markdown format covering beginner, advanced, some architecture/design
thoughts, and a glossary covering terms.

* De-Hadoop-ification / Personalities / Modules

By far, the largest change was a significant rewrite to create a core engine to enable pulling
out most/all of the Hadoop-specific settings and into a separate file.  This was done in order
to support many projects with different source layouts to use effectively the test-patch code
base.  As a result, the internals now use a concept of modules to dictate what to do where
rather than assuming that the root of the source repo is a valid location.

Project specific logic has been pushed into plugins we call 'personalities'.  Personalities
allow projects to dictate flags and ordering as well as perform other actions as needed before
tests execute.  As a result, there are several early personalities for flink, hbase, tajo,
and tez bundled.

* Docker support

Initial support for test-patch to switch to a dedicated docker container during execution,
including the ability to provide a custom Dockerfile. 

* Multiple build systems

Support for ant with the groundwork laid to support more.  An early version of a pig personality
is included to use this functionality.

* Multiple JDKs

It is possible to specify multiple JDKs to run supported tests. Built-in tests that support
multiple JDKs are javac, javadoc, and unit.  

* Multiple bug system support

Preliminary work to enable supporting bug tracking systems beyond Apache's JIRA system has
been introduced. A prototype github PR support plugin is bundled. Additionally, large parts
of the JIRA support have been pulled out into a separate plugin.

* API and variable renames/cleanups

Many, many changes to the names of variables and functions to be less Hadoop-specific and
just overall better.  As a result, this is a breaking change for any plugins written against
the old bits. 

Additionally, many interface stabilities have changed as a result.

MINOR:

* A compile+install has been added as the first test step to populate the maven repo with
the current code base, skipping over any failed compiles. This will help stabilize build predictability
in between runs with different patches.

* findbugs and ASF license checks have been moved to plug-ins

* smart-apply-patch has a stray rm fixed.

* File names of generated test logs, etc, that use the core engine are now consistent across
tests.

* JIRA output is now colored across the entire line, making it easier to spot failing tests.

* Warn about old versions of shellcheck, because there are some false positives with it.

* New files are now handled properly.

* Deleted modules and files should be handled better.

* Off-by-one errors in the git diff line listing should fix false positives in a few reports.

* whitespace now errors on tabs in files not named Makefile.

* xml files are now validated.

* bash version check has been added to prevent running on older versions.

* Some tests now default to a summary report rather than listing all results.

* In order to prepare for eventual split, many defaults have been changed to be yetus-specific
rather than Hadoop specific.

* Eliminated egrep usage in favor of grep -E

* Many additions/cleanups to report output.

* Plugins can now add output to the usage message.

* test-patch temp directory has been renamed.

* wget errors are more specific now.
