[jira] [Created] (SPARK-9608) Incorrect zinc -status check in build/mvn

Ryan Williams created SPARK-9608:
------------------------------------

             Summary: Incorrect zinc -status check in build/mvn
                 Key: SPARK-9608
                 URL: https://issues.apache.org/jira/browse/SPARK-9608
             Project: Spark
          Issue Type: Bug
          Components: Build
    Affects Versions: 1.4.1
            Reporter: Ryan Williams


{{build/mvn}} [uses a {{-z `zinc -status`}} test|https://github.com/apache/spark/blob/5a23213c148bfe362514f9c71f5273ebda0a848a/build/mvn#L138] to determine whether a {{zinc}} process is running.

However, {{zinc -status}} checks port {{3030}} by default.

This means that if a {{$ZINC_PORT}} env var is set to some value besides {{3030}}, and an existing {{zinc}} process is running on port {{3030}}, {{build/mvn}} will skip starting a {{zinc}} process, thinking that a suitable one is running.

Subsequent compilations will look for a {{zinc}} at port {{$ZINC_PORT}} and not find one.

The {{zinc -status}} call should get the flag {{-port "$ZINC_PORT"}} added to it.
