Hey @mateiz, thanks for reviewing the code. I read your comment about the
directory's name on tachyon. Yes, your concern about the driver's directory
name is right. We indeed need a unique top-level directory name here. The
reason why I made each executor's directory name to be the appID is to make it
better to be shared across SparkContexts in our future plan. I will follow the
directory organization of your solution at our current stage.
If your project is set up for it, you can reply to this email and have your
reply appear on GitHub as well. To do so, please top-post your response.
If your project does not have this feature enabled and wishes so, or if the
feature is enabled but not working, please contact infrastructure at
infrastruct...@apache.org or file a JIRA ticket with INFRA.
