Hello Xiaoyong, Could you shed more light on the problems you have been encountering ( and with which version of the hadoop )? Some of the details on how to use YARN timeline are documented here: http://tez.apache.org/tez_yarn_timeline.html - let me know if that helps. Let us also know what version of Tez you are trying and we can guide you further.
Beyond that, assuming you manage to get Tez to write data correctly to YARN timeline, the UI as you mentioned is JS based but it is built on top of the YARN timeline web services. There is some initial info on how to setup the UI here: https://github.com/apache/tez/blob/master/tez-ui/README.TXT. If you face any issues using the instructions, please do let us know as this will get refined as we get closer to the 0.6 release in the next few weeks. Some of the web service calls can be found in app/scripts/models/TimelineRestAdapter.js. For the most part, all the data is retrieved via these endpoints: <TIMELINEHOST:PORT>/ws/v1/timeline/TEZ_APPLICATION <TIMELINEHOST:PORT>/ws/v1/timeline/TEZ_DAG_ID <TIMELINEHOST:PORT>/ws/v1/timeline/TEZ_VERTEX_ID <TIMELINEHOST:PORT>/ws/v1/timeline/TEZ_TASK_ID <TIMELINEHOST:PORT>/ws/v1/timeline/TEZ_TASK_ATTEMPT_ID ( timeline usually runs on port 8188 by default ) thanks — Hitesh On Dec 12, 2014, at 2:21 AM, Xiaoyong Zhu <xiaoy...@microsoft.com> wrote: > Hi Tez experts > > I am really excited to see the Tez UI will be coming out in 0.6! it’s really > helpful! > I want to try that in my local sandbox (Cloudera/Hortonworks) but I > encountered a lot of issues (such as cannot find > org.apache.tez.dag.history.logging.ats packages) and I decide to give up > building it myself.
