This moves Hadoop to Apache commons-collections4.
Apache commons-collections has been removed and is completely banned from the source code.

To support YARN deployments in clusters without HDFS
some changes have been made in packaging
* new hadoop-common class org.apache.hadoop.fs.HdfsCommonConstants
* hdfs class org.apache.hadoop.hdfs.protocol.datatransfer.IOStreamPair moved
from hdfs-client to hadoop-common
* YARN handlers for DSQuotaExceededException replaced by use of superclass
ClusterStorageCapacityExceededException.

* Use Yetus 0.14.1 from downloads.apache.org in yetus-wrapper
* Use Maven 3.8.8 from downloads.apache.org in Win 10 Dockerfile
* Point users to downloads.apache.org for JVSC
* Use Solr 8.11.2 from downloads.apache.org in YARN Dockerfile

Exclude more artifacts which are dependencies of hadoop-* modules,
with the goal of keeping conflict out of downstream applications.
In particular we have pruned the dependencies of of:
-zookeeper
-other libraries referencing logging
This keeps slf4j-log4j12 and log4j12 off the classpath
of applications importing hadoop-common.
Somehow logback references do still surface; applications
pulling in hadoop-common directly or indirectly should
review their imports carefully.

Includes HADOOP-18354. Upgrade reload4j to 1.22.2 due to XXE vulnerability (#4607).
Log4j 1.2.17 has been replaced by reloadj 1.22.2
SLF4J is at 1.7.36
Protobuf 2.5 JAR is no longer needed at runtime.
The option common.protobuf.scope defines whether the protobuf 2.5.0
dependency is marked as provided or not.
* New package org.apache.hadoop.ipc.internal for internal only protobuf classes
...with a ShadedProtobufHelper in there which has shaded protobuf refs
only, so guaranteed not to need protobuf-2.5 on the CP
* All uses of org.apache.hadoop.ipc.ProtobufHelper have
been replaced by uses of org.apache.hadoop.ipc.internal.ShadedProtobufHelper
* The scope of protobuf-2.5 is set by the option common.protobuf2.scope
In this patch is it is still "compile"
* There is explicit reference to it in modules where it may be needed.
* The maven scope of the dependency can be set with the common.protobuf2.scope
option. It can be set to "provided" in a build:
-Dcommon.protobuf2.scope=provided
* Add new ipc(callable) method to catch and convert shaded protobuf
exceptions raised during invocation of the supplied lambda expression
* This is adopted in the code where the migration is not traumatically
over-complex. RouterAdminProtocolTranslatorPB is left alone for this
reason.

All uses of jersey-json in the yarn and other hadoop modules now
exclude the obsolete org.codehaus.jettison/jettison and so avoid
all security issues which can come from the library.

As well as the POM update, this patch moves to the (renamed) verify methods.
Backporting mockito test changes may now require cherrypicking this patch, otherwise
use the old method names.

This downgrades jackson from the version switched to in
HADOOP-18033 (2.13.0), to Jackson 2.12.7.
This removes the dependency on javax.ws.rs-api,
so avoiding runtime problems with applications using
jersey-core v1 and/or jsr311-api.
The 2.12.7 release still contains the fix for CVE-2020-36518.
