Next try. I copied whole dist directory created by make-distribution script
to cluster not just assembly jar. Then I used
./bin/spark-submit --num-executors 200 --master yarn-cluster --class org.
apache.spark.mllib.CreateGuidDomainDictionary ../spark/root-0.1.jar ${args}
...to run app again. Startup scripts printed this message:
"Spark assembly has been built with Hive, including Datanucleus jars on
classpath"
...so I thought I am finally there. But job started and failed on the same
ClassNotFound exception as before. Is "classpath" from script message just
classpath of driver? Or is it the same classpath which is affected by --jars
option? I was trying to find out from scripts but I was not able to find
where --jars option is processed.
thanks

Bonus question: Should the class org.datanucleus.api.jdo.
JDOPersistenceManagerFactory be part of assembly? Because it is not in jar
now.

No these jars cannot be put into the assembly because they have extra
metadata files that live in the same location (so if you put them all in an
assembly they overrwrite each other). This metadata is used in discovery.
Instead they must be manually put on the classpath in their original form
(usually using --jars).
