Sunil G commented on YARN-7088: ------------------------------- IIUC, there are few fields we are trying to define based on trunk as well as this patch. ||Types||Definition||Calculation|| |*submitTime*|Submission time of app from ClientRMService#submitApplication|N/A| |*startTime*|When RMApp is created in RMAppManager during submission of an app|N/A| |launchTime|When RM has allocated master container for AM and RMAppAttempt reaches LAUNCHED state|N/A| |*finishTime*|When AM un-registered or RMApp's end time in case of failure|N/A| |*elapsedTime*|Time difference between app start and finish|finishTime-startTime| |schedulingWaitTime/pendingTime|Time difference between app launch and start time to get scheduling wait time|launchTime-startTime| |totalRunTime|Time difference between app launch and finish so that we get whole run time|finishTime-launchTime| We have some of this fields which are marked bold and other proposed in this patch except *totalRunTime*. I think addition of *launchTime* makes sense. *pendingTime* was lil confusing as it was not clear what it was pending for. I was also thinking *schedulingWaitTime* is more clear than pendingTime. If others feels pendingTime fine, i think i am also good, lets get this in :). I am looping [~rohithsharma] who worked in App Timeout feature if he has some more thoughts. Please correct me and update if any definitions are not correct. By the way I have another major query though, during recovery how could we save *launchTime*. We cannot change this value after RM restart as APP may be already running. Recovery might need a relook with respect to launchTime. > Fix application start time and add submit time to UIs > ----------------------------------------------------- > > Key: YARN-7088 > URL: https://issues.apache.org/jira/browse/YARN-7088 > Project: Hadoop YARN > Issue Type: Bug > Affects Versions: 3.0.0-alpha4 > Reporter: Abdullah Yousufi > Assignee: Abdullah Yousufi > Attachments: YARN-7088.001.patch, YARN-7088.002.patch, > YARN-7088.003.patch, YARN-7088.004.patch, YARN-7088.005.patch, > YARN-7088.006.patch, YARN-7088.007.patch > > > Currently, the start time in the old and new UI actually shows the app > submission time.
