Re: Building standalone spark application via sbt

[Sachin Mittal]

I got the error during run time. It was for mongo-spark-connector class
files.
My build.sbt is like this

name := "Test Advice Project"
version := "1.0"
scalaVersion := "2.10.6"
libraryDependencies ++= Seq(
"org.mongodb.spark" %% "mongo-spark-connector" % "1.0.0",
"org.apache.spark" %% "spark-core" % "1.6.1" % "provided",
"org.apache.spark" %% "spark-sql" % "1.6.1" % "provided"
)

assemblyMergeStrategy in assembly := {
   case PathList("META-INF", xs @ _*) => MergeStrategy.discard
   case x => MergeStrategy.first
}

and I create the fat jar using sbt assembly
I have also added addSbtPlugin("com.eed3si9n" % "sbt-assembly" % "0.14.3")
in ~/.sbt/0.13/plugins/plugins.sbt for sbt assembly to work.

I think when you use provided it does not include those jars in your fat
jar.

I am using spark 1.6

Thanks
Sachin

Re: Building standalone spark application via sbt

[Marco Mistroni]

 that will work but ideally you should not include any of the
spark-releated jars as they are provided to you by the spark environment
whenever you launch your app via spark-submit (this will prevent unexpected
errors e.g. when you kick off your app using a different version of spark
where some of the classes has been renamd or movedaround -tbh i don't think
this is a case that happen often)

Btw did you get the NoClassDefFoundException at compile time or run time?if
at run time, what is your Spark Version  and what is the spark libraries
version you used in your sbt?
are you using a Spark version pre 1.4?

Re: Building standalone spark application via sbt

[Sachin Mittal]

NoClassDefFound error was for spark classes like say SparkConext.
When running a standalone spark application I was not passing external jars
using --jars option.

However I have fixed this by making a fat jar using sbt assembly plugin.

Now all the dependencies are included in that jar and I use that jar in
spark-submit

Thanks

 Whether you need spark-sql depends on whether you will use the
 DataFrame API. Without spark-sql, you will just have the RDD API.

Hello Sachin

For an extremely simple case, let's assume  you have your  MyFirstSparkApp

Then all you need to do would be to kick off

spark-submit --class MyFirstSparkApp   myFirstSparkApp.jar

if you have any external dependencies (not spark , let's assume you are

you need an uber jar file.

Have you actually followed the dependencies and project sub-directory build?

Re: Building standalone spark application via sbt

[Sachin Mittal]

Hi,
I am following the example under
https://spark.apache.org/docs/latest/quick-start.html
For standalone scala application.

I added all my dependencies via build.sbt (one dependency is under lib
folder).

When I run sbt package I see the jar created under
target/scala-2.10/

So compile seems to be working fine. However when I inspect that jar, it
only contains my scala class.
Unlike in java application we build a standalone jar, which contains all
the dependencies inside that jar, here all the dependencies are missing.

So as expected when I run the application via spark-submit I get the
NoClassDefFoundError.

Here is my build.sbt

name := "Test Advice Project"
version := "1.0"
scalaVersion := "2.10.6"
libraryDependencies ++= Seq(
"org.apache.spark" %% "spark-core" % "1.6.1",
"org.apache.spark" %% "spark-sql" % "1.6.1"
)

Can anyone please guide me to as what is going wrong and why sbt package is
not including all the dependencies jar classes in the new jar.

Thanks
Sachin

Re: Building standalone spark application via sbt

[Andrew Ehrlich]

Yes, spark-core will depend on Hadoop and several other jars.  Here’s the list 
of dependencies: https://github.com/apache/spark/blob/master/core/pom.xml#L35 


Whether you need spark-sql depends on whether you will use the DataFrame API. 
Without spark-sql, you will just have the RDD API.
