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

             Summary: spark-daemon.sh fails on long classpath
                 Key: SPARK-6952
                 URL: https://issues.apache.org/jira/browse/SPARK-6952
             Project: Spark
          Issue Type: Bug
          Components: Deploy
    Affects Versions: 1.3.0
            Reporter: Punya Biswal


{{sbin/spark-daemon.sh}} uses {{ps -p "$TARGET_PID" -o args=}} to figure out whether the process running with the expected PID is actually a Spark daemon. When running with a large classpath, the output of {{ps}} gets truncated and the check fails spuriously.

I think we should weaken the check to see if it's a java command (which is something we do in other parts of the script) rather than looking for the specific main class name. This means that SPARK-4832 might happen under a slightly broader range of circumstances (a *java* program happened to reuse the same PID), but it seems worthwhile compared to failing consistently with a large classpath.
