Akira AJISAKA commented on YARN-2123:
-------------------------------------
bq. Could you check whether this problem happens against current trunk?
I checked this problem happened against current trunk (revision 618ba7).
bq. One problem I found is the percentage of the app queue gets NaN - please
check an attached file. Is this related issue?
Probably it's because the used memory was divided by 0 in the following code:
{code:title=FairSchedulerQueueInfo.java}
fractionMemUsed = (float)usedResources.getMemory() /
clusterResources.getMemory();
{code}
Would you attach your yarn-site.xml and fair-scheduler.xml?

> In our cluster setup, the YARN web UI always shows progress bars at 100% (see
> screenshot, progress of the reduce step is roughly at 32.82%). I opened the
> HTML source code to check (also see screenshot), and it seems the problem is
> that it uses a comma as decimal mark, where most browsers expect a dot for
> floating-point numbers. This could possibly be due to localized number
> formatting being used in the wrong place, which would also explain why this
> bug is not always visible.
