------------------------------------
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.
