      Description

      here is nodemanager log of a host where a HBASE_REGIONSERVER component is running

      2016-01-12 14:11:49,237 DEBUG monitor.ContainersMonitorImpl (ContainersMonitorImpl.java:run(361)) - Current ProcessTree list : [ 9801 ]

      used memory for the container is lower than i expected.
      because pids ( 9801 9806 ) are slider-agent process. regionserver process was excepted from monitoring.

      here is the result of "ps axjf"

      when i use the ProcfsBasedProcessTree (default)
      process-tree is determined by relationship between parent and child process.
      so, daemonized process (ppid=1) can’t be included in process-tree.

      I don't know it can be fixed in slider.
      does it need to implement another ResourceCalculatorProcessTree to replace the ProcfsBasedProcessTree?
