I have a Hadoop cluster in my data center, can I run CDAP that uses my Hadoop cluster?

I'm seeing log messages about the failure to send audit log message while running the Sandbox. What's wrong?

If your computer goes into sleep mode, then you may see these messages after the machine is restored from sleep mode, as the audit logs are not getting delivered while the machine sleeps. You may need to restart CDAP to restore its state depending on how long it has been asleep.

You can use the CDAP User GoogleGroup to report issues or file a ticket using the available CDAP JIRA system.

What User Groups and Mailing Lists are available about CDAP?

The cdap-user mailing list is primarily for users using the product to develop applications. You can expect questions from users, release announcements, and any other discussions that we think will be helpful to the users.

The cdap-dev mailing list is essentially for developers actively working on the product, and should be used for all our design, architecture and technical discussions moving forward. This mailing list will also receive all JIRA and GitHub notifications.
