The primary motivation to relicense is a desire to integrate with projects
that are licensed under the Apache License version 2.0. Although opinions
vary, there are some who argue the the LGPL-2.1 and Apache-2.0 licenses
are not fully compatible. We would like to avoid the ambiguity and
potential for controversy.
Projects we would like to consume that are Apache-2.0 licensed include
Seastar, OpenSSL (which is in the process of relicensing to Apache-2.0),
and Swagger (swagger.io). Note that some of these are dynamically linked
or consumed via a high-level language and may or may not require a change
to LGPL-3.0, but providing the option for LGPL-3.0 certainly avoids any
uncertainty.
A few other source files are already incorporated into Ceph that claim an
Apache-2.0 license:
src/common/deleter.h
src/common/sstring.h
src/include/cpp-btree
The Ceph developers would further like to provide a license option that is
more modern than the current LGPL-2.1. LGPL-3.0 includes updated,
clarified language around several issues and is widely considered
more modern, superior license.

Back in commit 7469f26a33 when the COPYING
file was added to the repository and the project was "licensed," the
license file was
GNU LESSER GENERAL PUBLIC LICENSE
Version 2.1, February 1999
However, the license was abbreviated as LGPL2 in various places (pretty
much everywhere, actually), due to my own ignorance/carelessness. (I was
distinguishing it from shiny new version 3, released 6 months earlier.)
Version 2 of LGPL is the "Library General Public License," published in
June 1991: https://www.gnu.org/licenses/old-licenses/lgpl-2.0.html
Note that this ambiguity persists for most of the project's lifetime. For
example, the original debian/copyright in 8adc9dac1d
said "LGPL2" bug in 4545f8b929 (2009, a year
later) it is changed to LGPL2.1 to satisfy Debian's lintian checks. (It's
remained LGPL2.1 ever since.)
"Correct" the record by changing LGPL2 references to LGPL2.1.

The license applicable to the files under doc/ was originally declared (in the
top-level file COPYING) to be "Creative Commons Attribution-ShareAlike (CC
BY-SA)" by ed0653b493
This license declaration omitted a version number.
Some time later ef7418421b was merged, mentioning
CC-BY-SA-1.0 as one of the Ceph source code licenses. Although the purpose of that
commit was only to summarize the canonical license information from COPYING, it
unintentionally became the only place in the source code where the doc license
version was specified.
In March 2018, the Debian project warned that CC-BY-SA-1.0 does not meet its
criteria for inclusion in the "free" section of the Debian distribution. (For
that, at least version 3.0 must be used.)
This new commit removes the doc license ambiguity by setting it to CC-BY-SA-3.0
in all places where the license is mentioned.
The exact spelling of the license name is taken from https://spdx.org/licenses/

find_package(lttng-ust REQUIRED) fails to find the lttng library without
this change. because find_path(LTTNG_LIBRARY_DIR ...) does not search
in the default library paths. and the second mode of
FIND_PACKAGE_HANDLE_STANDARD_ARGS() does not stop the cmake with a fatal
message, even some of the required vars are missing. so use the
implemetantion from cmake upstream.

The in-tree Hadoop shim was a combination of libcephfs wrapper, and the
bits to support Hadoop. This has been replaced by src/java that
implements generic libcephfs wrappers, and externally, the hadoop shim
(see docs).

This is lightweight and relies on boost spirit, which we already use, so
there are no new dependencies.
There were some other libraries that also looked good, but they weren't
already packages for existing Debian distros like squeeze or even wheezy.
