+# Azure HDInsight Solutions | Spark | IllegalArgumentException
+
+## Scenario: Spark activity running in Azure Data Factory fails with IllegalArgumentException
+
+## Issue
+
+You receive the following exception when trying to execute a Spark activity in an Azure Data Factory pipeline:
+
+```java
+Exception in thread "main" java.lang.IllegalArgumentException: 
+Wrong FS: wasbs://additional@xxx.blob.core.windows.net/spark-examples_2.11-2.1.0.jar, expected: wasbs://wasbsrepro-2017-11-07t00-59-42-722z@xxx.blob.core.windows.net
+```
+
+## Cause
+
+A Spark job will fail if the application jar file is not located in the Spark cluster’s default/primary storage.
+
+This is a known issue with the Spark open source framework tracked in this bug: [Spark job fails if fs.defaultFS and application jar are different url](https://issues.apache.org/jira/browse/SPARK-22587)
+
+This issue has been resolved in Spark 2.3.0
+
+## Solution
+
+Make sure the application jar is stored on the default/primary storage for the HDInsight cluster. In case of Azure Data Factory make sure the ADF linked service is pointed to the HDInsight default container rather than a secondary container.
