Kyle Weaver created BEAM-8293:
---------------------------------

             Summary: Document or log file system issues with docker
                 Key: BEAM-8293
                 URL: https://issues.apache.org/jira/browse/BEAM-8293
             Project: Beam
          Issue Type: Improvement
          Components: java-fn-execution
            Reporter: Kyle Weaver
            Assignee: Kyle Weaver


A frequently asked question about portability in the mailing list is, "Why am I getting IOExceptions in my job?" where the answer is often, because the SDK harness is using docker, which does not have access to the local filesystem by default, so when users try to read/write via transforms or don't set a artifact_staging_location, they get errors. We should at least document this on the website. Even better would be to log something, especially for artifact_staging_location, which is implicit and users might not be aware of.
