--------------------------------------
Summary: Put examples packaging on a diet
Key: SPARK-14744
URL: https://issues.apache.org/jira/browse/SPARK-14744
Project: Spark
Issue Type: Improvement
Components: Examples
Affects Versions: 2.0.0
Reporter: Marcelo Vanzin
Priority: Minor
Currently the examples bring in a lot of external dependencies, ballooning the
size of the Spark distribution packages.
I'd like to propose two things to slim down these dependencies:
- make all non-Spark, and also Spark Streaming, dependencies "provided". This
means, especially for streaming connectors, that launching examples becomes
more like launching real applications (where you need to figure out how to
provide those dependencies, e.g. using {{--packages}}).
- audit examples and remove those that don't provide a lot of value. For
example, HBase is working on full-featured Spark bindings, based on code that
has already been in use for a while before being merged into HBase. The HBase
example in Spark is very bare bones and, in comparison, not really useful and
in fact a little misleading.
