    Description

      Hi Team,

       

      We are working on storm upgrade from 1.0.2 to 1.2.2. During upgrade, we realised that assigned memory displayed on Storm UI is incorrect. Attached screenshot for more details.

       

      Looks like assigned memory is sum of memory provided in topology.worker.childopts and topology.worker.logwriter.childopts options.

       

      Multiple scenarios we have observed where  assigned memory is not correct-

      1. If topology.worker.childopts memory is more than 3 GB, in this case assigned memory is showing 65 MB.
      1. If topology.worker.childopts memory+ topology.worker.logwriter.childopts memory is below 50 for last 2 digits.
        For eg.,
        topology.worker.childopts = 2048 MB
        topology.worker.logwriter.childopts = 64 MB
        Total = 2112 MB
        Here, last 2 digits are below 50, in this case assigned memory is showing 65 MB.
