[jira] [Commented] (STORM-3403) Incorrect Assigned memory displayed
on Storm UI
[ https://issues.apache.org/jira/browse/STORM-3403?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16875994#comment-16875994 ]
Nikhil commented on STORM-3403:
-------------------------------
Value of "topology.component.resources.onheap.memory.mb" config is 128.
Assigned memory is correct if we provide "topology.worker.childopts" as "-Xmx512m" and shows properly on UI as well. But if we provide 2048m, then assigned memory field is showing it as "65 MB".

> 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.
