Hi Hitrix,

Is your issue/scenario similar to YARN-2221 ?
like you have clicked a queue in scheduler page and then you come to Applications Page and
after that you are not able to see the Apps ?
In this case you will filtering being applied (as mentioned by Rohith). You can click on root
queue in scheduler page to rectify it

Do you remember the steps when applications won’t be displayed in RM web UI?  I mean after
which actions in the RM web UI applications are not displaying?

Is there any filtering is applied in the UI like “Showing 0 to 0 of 0 entries (filtered
from 4 total entries)” in the bottom of RM applications page?

Thanks & Regards

​Maybe you have hit the completed app limit (10000 by default). Once the limit hits, the
oldest completed app will be removed from cache.

Subject: Lost mapreduce applications displayed in UI


My cluster suddenly stopped displaying application information in UI (http://localhost:8088/cluster/apps).
Although the counters like 'Apps Submitted' , 'Apps Completed', 'Apps Running'  etc, all seems
to increment accurately and display right information, whnever I start new mapreduce job.

Any help is appreciated.
