To avoid the error you need to increase the Drill direct memory setting in the
drill-env.sh file, in /opt/mapr/drill/drill-1.0.0/conf
For the tomcat console/logs you need to configure the java app server settings
in tomcat. Don't have it in front of me, but it will be under tomcat-home/conf
or ../log directories. Just use the normal java app logging settings to spool
to a file instead of the console.
