------------------------------------

             Summary: Incorrect zinc check in build/mvn
                 Key: SPARK-9607
                 URL: https://issues.apache.org/jira/browse/SPARK-9607
             Project: Spark
          Issue Type: Bug
          Components: Build
    Affects Versions: 1.4.1
            Reporter: Ryan Williams
            Priority: Minor


[This 
check|https://github.com/apache/spark/blob/5a23213c148bfe362514f9c71f5273ebda0a848a/build/mvn#L84-L85]
 in {{build/mvn}} attempts to determine whether {{zinc}} has been installed, 
but it fails to add the prefix {{build/}} to the path, so it always thinks that 
{{zinc}} is not installed, sets {{ZINC_INSTALL_FLAG}} to {{1}}, and attempts to 
install {{zinc}}.

This error manifests later because [the {{zinc -shutdown}} and {{zinc -start}} 
commands|https://github.com/apache/spark/blob/5a23213c148bfe362514f9c71f5273ebda0a848a/build/mvn#L140-L143]
 are always run, even if zinc was not installed and is running.
