Before Deploying the MapR PACC
Perform a series of checks on the platform and MapR cluster before deploying the MapR PACC.
Before you deploy a MapR PACC, or an application container based on the PACC, perform the following checks on the platform and MapR cluster.

Leveraging MapR-FS Storage for Application Persistence
The data associated with containers is typically not persistent. If you specify a MapR
mount path using MAPR_MOUNT_PATH
, any data written to the mounted directory
will be persisted to MapR file system. For example, you could create a symlink to the Apache log
directory and persist all log files in MapR file system.
If you specify a MapR mount path and if your hardware or application fails, re-launching the container in any location using the same Docker runtime environment variables will result in all pre-created data being available for use.
Security Considerations
You should be aware of security considerations for secure and non-secure clusters when using MapR PACCs. See Security Considerations for the MapR PACC.
