---------------------------------
Summary: Flink portable pipeline jars do not need to stage
artifacts remotely
Key: BEAM-8312
URL: https://issues.apache.org/jira/browse/BEAM-8312
Project: Beam
Issue Type: Improvement
Components: runner-flink
Reporter: Kyle Weaver
Assignee: Kyle Weaver
Currently, Flink job jars stage all artifacts by using the usual
BeamFileSystemArtifactRetrievalService [1]. However, since the manifest and all
the artifacts live on the classpath of the jar, and everything from the
classpath is copied to the Flink workers anyway, it should not be necessary to
do additional artifact staging. We could replace
BeamFileSystemArtifactRetrievalService in this case with a simple
ArtifactRetrievalService that just pulls the artifacts from the classpath.
