|
3 | | -These are template projects that illustrate how to build Spark Application written in Java or Scala |
4 | | -with Maven, SBT or Gradle which can be run on either DataStax Enterprise (DSE) or Apache Spark. The |
5 | | -example project implements a simple write-to-/read-from-Cassandra application for each language and |
6 | | -build tool. |
7 | | - |
8 | | -## Dependencies |
9 | | - |
10 | | -Compiling Spark applications depends on Apache Spark and optionally on Spark Cassandra Connector |
11 | | -jars. Projects `dse` and `oss` show two different ways of supplying these dependencies. Both |
12 | | -projects are built and executed with similar commands. |
13 | | - |
14 | | -### DSE |
15 | | - |
16 | | -If you are planning to execute your Spark Application on a DSE cluster, you can use the `dse` |
17 | | -project template which will automatically download (and use during compilation) all jars available |
18 | | -in the DSE cluster. Please mind the DSE version specified in the build file; it should should match |
19 | | -the one in your cluster. |
20 | | - |
21 | | -Please note that DSE projects templates are meant to be built with `sbt` 0.13.13 or newer. In case of |
22 | | -unresolved dependencies errors, please update `sbt` and than clean `ivy` cache (with |
23 | | -`rm ~/.ivy2/cache/com.datastax.dse/dse-spark-dependencies/` command) |
24 | | - |
25 | | -### OSS |
26 | | - |
27 | | -If you are planning to execute your Spark Application against Open Source Apache Spark and Open |
28 | | -Source Apache Cassandra, use the `oss` project template where all dependencies have to be specified |
29 | | -manually in build files. Please mind the dependency versions; these should match the ones in your |
30 | | -execution environment. |
31 | | - |
32 | | -For additional info about version compatibility please refer to the Spark Cassandra Connector |
33 | | -[Version Compatibility Table](https://github.com/datastax/spark-cassandra-connector#version-compatibility). |
34 | | - |
35 | | -### Additional dependencies |
36 | | - |
37 | | -Prepared projects use extra plugins so additional dependencies can be included with your |
38 | | -application's jar. All you need to do is add dependencies in the build configuration file. |
39 | | - |
40 | | -## Building & running |
41 | | - |
42 | | -### Sbt |
43 | | - |
44 | | -Task | Command |
45 | | --------------|------------ |
46 | | -build | `sbt clean assembly` |
47 | | -run (Scala) | `dse spark-submit --class com.datastax.spark.example.WriteRead target/scala-2.11/writeRead-assembly-0.1.jar` |
48 | | -run (Java) | `dse spark-submit --class com.datastax.spark.example.WriteRead target/writeRead-assembly-0.1.jar` |
49 | | - |
50 | | -### Gradle |
51 | | - |
52 | | -Task | Command |
53 | | ---------------------|------------ |
54 | | -build | `gradle shadowJar` |
55 | | -run (Scala, Java) | `dse spark-submit --class com.datastax.spark.example.WriteRead build/libs/writeRead-0.1-all.jar` |
56 | | - |
57 | | -### Maven |
58 | | - |
59 | | -Task | Command |
60 | | ---------------------|------------ |
61 | | -build | `mvn package` |
62 | | -run (Scala, Java) | `dse spark-submit --class com.datastax.spark.example.WriteRead target/writeRead-0.1.jar` |
63 | | - |
64 | | -Notes: |
65 | | - |
66 | | -1. The above command example are for DSE. To run with open source Spark, use `spark-submit` instead |
67 | | -2. Also see included example script [BuildTestAll.sh](BuildTestAll.sh) which runs all combinations |

70 | | -## Running Integrated Tests |
71 | | - |
72 | | -Integrated tests have been set up under a `test` task in each build system. To run |
73 | | -the tests, invoke the build system and then launch `test`. These tests demonstrate |
74 | | -how to run integrated embedded Cassandra as well as Local Spark from within your testing |
75 | | -environment. |
76 | | - |
77 | | -Currently only Scala Testing examples are provided. |
78 | | - |
79 | | -These tests should also function inside IDEs that are configured with the ability to run |
80 | | -the build system's tests. |
