--------------------------------------
Summary: Depend on packaged .jar files instead of copying .jar
files into every package
Key: BIGTOP-1797
URL: https://issues.apache.org/jira/browse/BIGTOP-1797
Project: Bigtop
Issue Type: Bug
Components: build
Reporter: Erich Schubert
Packages should *depend* on packaged .jar files, instead of including *copies*
of the jars in every package again and again.
Most packages would shrink substantially in size once these redundancies have
been removed. From a quick test, about 18 MB of a 20 MB package are shareable
.jar files!
Apache Commons, Jackson, Protobuf, etc.
all these exist as operating system packages (with security support etc.) on
most Linux distributions. There is *no need to include copies* of them inside
of hadoop packages (in fact, this violates the packaging policy of e.g. Ubuntu
and Debian)
Even worse, the files are sometimes even included more than once (and they
definitely are included in more than one package).
Where possible, the lib/ folder should consist of symlinks to the appropriate
jar files in /usr/share/java, and *dependencies* should be used to ensure these
jar files exist on the system. This way, they can be shared across different
applications.
