Examples of com.linkedin.helix.ExternalCommand

com.linkedin.helix.ExternalCommand
This class encapsulates a java Process to handle properly output and error and preventing potential deadlocks. The idea is that the command is executed and you can get the error or output. Simple to use. Should not be used for big outputs because they are buffered internally. @author ypujante@linkedin.com

    String testName = className + "_" + methodName;


    System.out.println("START " + testName + " at "
        + new Date(System.currentTimeMillis()));

    int j = output.indexOf("ms", i);
    long latency = Long.parseLong(output.substring(i, j));
    System.out.println("startup latency: " + latency);
