Alok, I had to install the Drill dependencies locally since they're not in maven central (DRILL-284 <https://issues.apache.org/jira/browse/DRILL-284>).
I did the following with drill-1.0.0: mvn install:install-file -Dfile=/opt/apache-drill-1.0.0/jars/drill-java-exec-1.0.0-rebuffed.jar -DgroupId=org.apache.drill.exec -DartifactId=drill-java-exec -Dversion=1.0.0 -Dpackaging=jar -DgeneratePom=true mvn install:install-file -Dfile=/opt/apache-drill-1.0.0/jars/drill-common-1.0.0-rebuffed.jar -DgroupId=org.apache.drill -DartifactId=drill-common -Dversion=1.0.0 -Dpackaging=jar -DgeneratePom=true Worked for me.
