Cluster deploy mode driver location

Hello there,

I have a Spark program in 1.6.1, however, when I submit it to cluster, it randomly picks the driver.

I know there is a driver specification option, but along with it it is mandatory to define many other options I am not familiar with. The trouble is, the .jars I am launching need to be available at the driver host, and I would like to have this jars in just a specific host, which I like it to be the driver.

Any help?

Thanks!
Saif

You may also try distributing your JARS along with your Spark app; see 
options below. You put on the client node whatever that is necessary and 
submit them all in each run. There is also a --files option which you can 
remove below, but may be helpful for some configs.

You do not need to specify all the arguments; the default values are 
picked up when not explicitly given.

spark-submit \
--master yarn \
--deploy-mode cluster \
--num-executors 2 \
--driver-memory 4g \
--executor-memory 8g \
--files /usr/hdp/current/spark-client/conf/hive-site.xml \
--jars 
/usr/hdp/current/spark-client/lib/datanucleus-api-jdo-3.2.6.jar,/usr/hdp/current/spark-client/lib/datanucleus-rdbms-3.2.9.jar,/usr/hdp/current/spark-client/lib/datanucleus-core-3.2.10.jar 
\
--class "SparkApp"  \
/pathToAppOnTheClientNode/SparkApp.jar (if any, arguments passed to the 
Spark App here)

Hi Saif!

Unfortunately, I don't think this is possible for YARN driver-cluster 
mode. Regarding the JARs you're referring to, can you place them on HDFS 
so you can then have them in a central location and refer to them that way 
for dependencies?

Thanks,
Silvio
