Can not load avro by packaging spark-avro_2.11 in jar

I use spark-submit to run a scala jar, it raise an error:

Exception in thread "main" org.apache.spark.sql.AnalysisException: Failed to find data source: avro. Avro is built-in but external data source module since Spark 2.4. Please deploy the application as per the deployment section of "Apache Avro Data Source Guide".;

the dependency is 

<groupId>org.apache.spark</groupId>
    <artifactId>spark-avro_2.11</artifactId>
<version>2.4.4</version>

it seems the avro dependency does not work.

But if I add --packages org.apache.spark:spark-avro_2.11:2.4.4 in spark-submit command, it can work.

Can you show your pom.xml files ? are you building fat jar ? I am thinking avro jar is not included in your final jar file & also can you unzip your final jar & check avro jar is available or not ? - Srinivas

Because org.apache.spark.spark-avro_2.11:2.4.4.jar jar file is not available in class path. try building fat jar which should contain all required spark-avro dependencies.

Also check if your cluster is having lower version of spark & avro version it might not work as expected.

Try adding below code to your pom.xml & change main class in this - <Main-Class>...</Main-Class>

   <execution>
      <phase>package</phase>
      <goals>
         <goal>shade</goal>
      </goals>
      <configuration>
         <finalName>${project.artifactId}</finalName>

                  <Main-Class>...</Main-Class> 
                  <X-Compile-Source-JDK>${maven.compile.source}</X-Compile-Source-JDK>
                  <X-Compile-Target-JDK>${maven.compile.target}</X-Compile-Target-JDK>
               </manifestEntries>
            </transformer>
            <transformer implementation="org.apache.maven.plugins.shade.resource.AppendingTransformer">

            </transformer>
