Known Issues for Cloud-Based Clusters

Before installing a MapR cluster in the cloud, be sure to review these known issues:

Issue	Description
IN-2012	An issue in the Java version used by the MapR Installer prevents the Installer from supporting a domain suffix that starts with a number. Azure generates a random string for the domain suffix, so this problem can occur intermittently. Workaround The `mapr-setup.sh` script checks for the DNS Suffix during installation and fails with an error similar to the following when the suffix begins with a number. If you see this error message, create new nodes and retry the installation with a DNS Suffix that does not start with a number. `ERROR: The DNS Suffix 14x325z0ek4ezp1skptqsztkyg.dx.internal.cloudapp.net starts with a number which is incompatible with OpenJDK keytool application. This cluster is invalid. Recreate the cluster again; DNS Suffix is 14x325z0ek4ezp1skptqsztkyg.dx.internal.cloudapp.net; First character of DNS Suffix is: 1\n\.`
IN-860	If you create a cluster using a MapR marketplace offering for Amazon AWS and use ephemeral drives, and you then shut down the cluster, most MapR services cannot be restarted. This happens because the disks are new, and the MapR cluster is not aware of the ephemeral drives. Workaround: Do not use clusters with ephemeral drives, or do not shut down the cluster. When the cluster is not in use, terminate it.
IN-974	If you request public IP addresses for the MapR Installer nodes in Amazon AWS, the IP addresses can change after a shutdown and restart of the cluster, and the MapR Installer status page continues to display the old public IP addresses. Workaround: None.
