    • Component/s: Tool/nodetool

      1000 M1.Large Ubuntu 12.04

    • Severity:
      Low

      Description

      Nodetool status on a 1000 Node cluster without vnodes returns in several seconds. With vnodes on (256) there are OOM errors with the default XMX of 32. Adjusting the XMX to 128 allows nodetool status to complete but the execution takes roughly 10 minutes.

      Tested

      XMX    |      Status
      32     |    OOM
      64     |    OOM: GC Overhead
      128    |    Finishes in ~10 minutes
      500    |    Finishes in ~10 minutes
      1000   |    Finishes in ~10 minutes
