Chesnay Schepler closed FLINK-2247.
    Resolution: Invalid

We no longer show such warnings in the WebFrontend. We are also showing the 
amount of managed memory and total JVM memory.

> Improve the way memory is reported in the web frontend

>                 Key: FLINK-2247
>                 URL: https://issues.apache.org/jira/browse/FLINK-2247
>             Project: Flink
>          Issue Type: Improvement
>          Components: Webfrontend
>            Reporter: Theodore Vasiloudis
>            Priority: Trivial
> Currently in the taskmanager view of the web frontend, the memory available 
> to Flink is reported in a slightly confusing manner.
> In the worker summary, we get a report of the Flink Managed memory available, 
> and we get warnings when that is set too low.
> The warnings though seem to be not taking the memory available to Flink when 
> being issued.
> For example, in a machine with 7.5GB memory available it is normal to assign 
> ~6GB for the JVM, which under default settings gives ~4GB to Flink managed 
> memory.
> In this case however, we get a warning that 7500MB of memory is available, 
> but only ~$4000MB is available to Flink, disregarding the total amount 
> available to the JVM.
> The reporting can then be improved by reporting the total amount available 
> for the JVM, the amount available for Flink's managed memory, and only issue 
> warnings when the settings are actually low compared to the available memory.
