--------------------------------------
Summary: Shade protobuf dependency in Mesos Java library
Key: MESOS-1203
URL: https://issues.apache.org/jira/browse/MESOS-1203
Project: Mesos
Issue Type: Improvement
Components: build
Reporter: Patrick Wendell
Mesos's Java library uses the protobuf library which is also used by Hadoop.
Unfortunately the protobuf library does not provide binary compatiblity between
minor versions (for code compiled against 2.4.1 and 2.5.0 cannot run together
in a single JVM classlaoder) .
This makes use of Mesos via it's Java API, something that is required for Spark
and I'm assuming other frameworks, fundamentally incompatible for certain
Hadoop versions.
Mesos could shade this jar using the maven shade plug-in. Take a look at the
Parquet project for an example of shading:
https://github.com/Parquet/parquet-mr/blob/master/pom.xml#L198
Without this fix Java users won't be able to use Mesos (< 0.17) with newer
versions of Hadoop.
