Hello All,
I am trying to launch my app on Apex/DT 3.3 version running on top of CDH
5.7. I tried on DT/Apex 3.2 as well running on CDH 5.7. Both these
deployments show the following behavior. (We have a requirement to run Apex
on CDH 5.7 )
I was wondering if you could advise on any workarounds for the following
issue:
I am not able to see any metrics in the web console when I open the
"Monitor" section. The application code seems to be working fine as I see
data flow happening fine as expected. However I see no metrics ( even the
top level container metrics) .
One more observed issue is that when I click on the container ID from the
monitor section, the UI crashes. ( In the sense the UI simply does not show
anything ). I am however able to get some preliminary UI ( barring the
metrics ) if I click on the container link from the monitor section if the
application is in the "ACCEPTED" state. The container link does not work
the moment the app moves from ACCEPTED to Running State.
The DtGateway shows the following logs :
