`heron submit ... --config-property heron.classpath.instance=<path-to-class> ..` This option is passed to heron-executor which launches heron-instance with the specified class path. For a general container, it needs two tar.gz: heron-core.tar.gz and topology.tar.gz. heron-instance is only a small part of heron-core.tar.gz, which I do not think pre-installed heron-instance class path can save much time. For topology.tar.gz, pre-installed class path may save lots of time depending on your job lib size. At present there is only one classpath for heron-instance, in other words, the heron-instance-itself class-path and user-job-class-path are the same classpath. #1735 two class paths are a candidate solution. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
