Introduced in SOLR-14033 by including
commons-compress as a compile time
dependency in Solr core instead of as
as test only dependency.

* Better logging and error reporting
* Fixing deploy command to handle previously undeployed packages
* Test now uses @LogLevel annotation
* Deploy command had a hard coded collection name by mistake, fix it
* split "resource-and-plugin-loading.adoc" into "resource-loading.adoc" and "libs.adoc" then overhauled both.
* enhanced "config-sets.adoc", moving some content in from elsewhere; bit of an overhaul.
* solr-plugins.adoc is now top-level; overhauled content
* Move resource-loading.adoc up a level in the TOC to underneath "The Well-Configured Solr Instance.
* Separate out the leading sentence.
(cherry picked from commit 7c048c5070988f35d38d5f592fad5d295ddb380a)

Some permissions and build hacks were made on behalf of hadoop: hacks on
top of hacks. Now that the major problems such as classpath pollution and
hadoop test code are fixed, so we can remove hacks built on top of them.
The default configset no longer has the following:
- Library inclusions (<lib ../>) for extraction, solr-cell libs, clustering, velocity and language identifier
- /browse, /tvrh and /update/extract handlers
- TermVector component (if someone wants it, can be added using config APIs)
- XSLT response writer
- Velocity response writer
If you want to use them in your collections, please add them to your configset manually or through the Config APIs.
* Using collapse with grouping would cause inconsistent behavior.
This is because grouping calls the same postfilter twice without
resetting the internal state of the DocValues cache
* Using expand with grouping would cause NPE
previously, entire classpath of ant (ant itself, plugins, ivy, etc) were
polluting the unit tests classpath. it leads to non-reproducible build
issues because tests classpath is different depending on things outside
of source code control.
for example, solr tests launching hadoop, hadoop launching jetty, jetty
scanning classpath -> boom
Solr tests now have a similar policy to Lucene, loopback use only. If a
test tries to resolve or connect to the internet, it will get SecurityException.
Some solr tests explicitly try to talk to dead nodes with real
networking. This is not good and asking for trouble, but use low loopback port numbers instead of
multicast addresses. The idea is that it fails faster. Move these to
constants so that stuff isn't copy-pasted everywhere, in case we have to
do something different later.
This removes the Solr security manager hacks
for Hadoop. It does so by:
* Using a fake group mapping class instead of ShellGroupMapping
* Copies a few Hadoop classes and modifies them for tests with no Shell
* Nulls out some of the static variables in the tests
The Hadoop files were copied from Apache Hadoop 3.2.0
and copied to the test package to be only picked up
during tests. They were modified to remove the need to
shell out for access. The assumption is that these
HDFS integration tests only run on Unix based systems
and therefore Windows compatibility was removed in some
of the modified classes. The long term goal is to remove
these custom Hadoop classes. All the copied classes are
in the org.apache.hadoop package.
