Hi, I have a question about the yarn and timeLineServer: when a task-map fails to connect to time line server and update her status, it is killed by the resource manager ? I had a problem with the application master, i sawed 155 attempts killed and only the last map has succeeded. For all the 155 attempts, i saw on the le log the same following error: 2016-09-21 10:10:33,549 INFO [ATS Logger 0] hooks.ATSHook (ATSHook.java:run(136)) - Failed to submit plan to ATS: java.lang.RuntimeException: Failed to connect to timeline server.
