Ethan Li commented on STORM-3403: --------------------------------- Please don't -Xmx in "topology.worker.childopts" directly. https://github.com/apache/storm/blob/v1.2.2/storm-core/src/jvm/org/apache/storm/Config.java#L1919 https://github.com/apache/storm/blob/v1.2.2/storm-core/src/jvm/org/apache/storm/Config.java#L1477 " %HEAP-MEM%" in "worker.childopts" will be replaced with the onheap memory settings. > Incorrect Assigned memory displayed on Storm UI > ----------------------------------------------- > > Key: STORM-3403 > URL: https://issues.apache.org/jira/browse/STORM-3403 > Project: Apache Storm > Issue Type: Bug > Components: storm-ui > Affects Versions: 1.2.2 > Reporter: Nikhil > Priority: Major > Attachments: componentsScreenshot.png, topologyAssignedMem.png > > Original Estimate: 24h > Remaining Estimate: 24h > > 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- > # If topology.worker.childopts memory is more than 3 GB, in this case > assigned memory is showing 65 MB. > # 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. -- This message was sent by Atlassian JIRA (v7.6.14#76016)
