List of updateProcessTree() Examples

Examples of updateProcessTree()

org.apache.hadoop.yarn.util.ProcfsBasedProcessTree.updateProcessTree()
Update process-tree with latest state. If the root-process is not alive, tree will be empty.
org.apache.hadoop.yarn.util.ResourceCalculatorProcessTree.updateProcessTree()
Update the process-tree with latest state. Each call to this function should increment the age of the running processes that already exist in the process tree. Age is used other API's of the interface.

Examples of org.apache.hadoop.yarn.util.ProcfsBasedProcessTree.updateProcessTree()

    Thread t = new RogueTaskThread();
    t.start();
    String pid = getRogueTaskPID();
    LOG.info("Root process pid: " + pid);
    ProcfsBasedProcessTree p = createProcessTree(pid);
    p.updateProcessTree(); // initialize
    LOG.info("ProcessTree: " + p.toString());


    File leaf = new File(lowestDescendant);
    //wait till lowest descendant process of Rougue Task starts execution
    while (!leaf.exists()) {
