Are you using ATS v1.5 or ATS v1? The tez app seems to have initialized with ATS v1 and the server seems to be of ATS v1.5.
Set: tez.history.logging.service.class=org.apache.tez.dag.history.logging.ats.ATSV15HistoryLoggingService and try again. — Thanks, Harish On 10-Dec-2016, at 12:46 AM, Madhusudan Ramanna <m.rama...@ymail.com<mailto:m.rama...@ymail.com>> wrote: Hello Tez folks, Tez UI (0.8.4) is able to communicate with RM and display application ids and completion status.

What could be happening here ? We switched out Tez UI with 0.8.4 with 0.9.0 (commit: c07ec7). However we saw errors like these on timeline server: java.io.IOException: History file for application application_1481155336218_0206 is not found We don't see this error while using Tez UI 0.8.4 Any pointers are greatly appreciated thank you, Madhu
