HI All,
Right now I'm trying to execute a script using this command:
nohup $SPARK_HOME/bin/spark-shell < $HOME/my-script.scala > $HOME/my-script.log
2>&1 &
my-script.scala just have 1 line of code:
println("hallo world")
But after waiting for a minute, I still don't receive the result from
spark-shell.
And the output log only contains:
Spark assembly has been built with Hive, including Datanucleus jars on classpath
SLF4J: Class path contains multiple SLF4J bindings.
SLF4J: Found binding in
[jar:file:/data1/hadoop/spark-1.0.0-bin-hadoop2/lib/spark-assembly-1.0.0-hadoop2.2.0.jar!/org/slf4j/impl/StaticLoggerBinder.class]
SLF4J: Found binding in
[jar:file:/data1/hadoop/hbase-0.96.0-hadoop2/lib/slf4j-log4j12-1.6.4.jar!/org/slf4j/impl/StaticLoggerBinder.class]
SLF4J: See http://www.slf4j.org/codes.html#multiple_bindings for an explanation.
SLF4J: Actual binding is of type [org.slf4j.impl.Log4jLoggerFactory]

My question is:
What is the right way to execute spark script?
I really want to use spark-shell as a way to run cron job in the future, just
like when I run R script.
Best regards,
Henry
