             Summary: Spark submit should ignore cache for SNAPSHOT dependencies
                 Key: SPARK-34757
                 URL: https://issues.apache.org/jira/browse/SPARK-34757
             Project: Spark
          Issue Type: Bug
          Components: Deploy, Spark Core
    Affects Versions: 3.1.1
            Reporter: Bo Zhang


When spark-submit is executed with --packages, it will not download the 
dependency jars when they are available in cache (e.g. ivy cache), even when 
the dependencies are SNAPSHOTs. 

This might block developers who work on external modules in Spark (e.g. 
spark-avro), since they need to remove the cache manually every time when they 
update the code during developments (which generates SNAPSHOT jars). Without 
knowing this, they could be blocked wondering why their code changes are not 
reflected in spark-submit executions.
