             Summary: Supporting integration test execution on remote machines
                 Key: SAMZA-508
                 URL: https://issues.apache.org/jira/browse/SAMZA-508
             Project: Samza
          Issue Type: Bug
          Components: test
            Reporter: Chris Riccomini


SAMZA-468 added support for single-node execution of integration tests. Multi-node integration tests don't work right now because of the way we're deploying job tarballs. We're using yarn.package.path=file:/... URI schemes, and SCP'ing the job tarballs to all machines. This is a problem when executing on multiple nodes because YARN stats the local job tarball when run-job.sh is run, and compares the tarball's [ctime/mtime/atime|http://www.linux-faqs.info/general/difference-between-mtime-ctime-and-atime] fields against the remote machines. They don't match since we're SCP'ing them, so YARN fails the job's deployment.

We'll have to either modify the remote timestamps, or use some other filesystem (HDFS, HTTP, etc) to deploy the job tarballs to YARN NMs.
