Tez UI with CDH

[Jan Morlock <ja...@googlemail.com>]

Hi,

we are using Tez 0.8.4 successfully both with Hive and Pig on our
Cloudera CDH 5.7.1 cluster. However so far we haven't managed yet to
properly integrate the Tez UI in our infrastructure.

The problem is not the UI itself but rather the fact, that it relies on
the Application Timeline Server:
the Application Timeline Server does not seem to be an essential part of
the CDH distribution. By default it seems to be switched off. Although
we managed to activate it, we failed to integrate it in our system in a
way, that it gets automatically populated with application data.

Similar problem descriptions from other users can be found at

Does anybody here have similar experiences and perhaps even find a
solution?

I am aware that the problem is slightly off-topic. None the less any
help is appreciated.

With best regards
Jan

Cloudera doesn't support the timeline server and it doesn't get updated
like other hadoop components despite there being upstream changes. There
are some bugs that prevent tez from properly working with the cdh timeline
server version. I'm not sure what the bug/lack of features are but my
solution to this was to run a timeline server using the vanilla hadoop
jars. I hope this helps.
