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()

      newProcInfos[0] = new ProcessStatInfo(new String[]
                      {"500", "proc5", "100", "100", "100", "500000", "500"});
      writeStatFiles(procfsRootDir, newPids, newProcInfos);


      // check memory includes the new process.
      processTree.updateProcessTree();
      Assert.assertEquals("Cumulative vmem does not include new process",
                   1200000L, processTree.getCumulativeVmem());
      long cumuRssMem = ProcfsBasedProcessTree.PAGE_SIZE > 0 ?
