Hi all, Has anyone a workaround for this problem ? I have exactly the same case. I have similar issues on the Sandbox 2.5 (VirtualBox-5.1.12-112440-Win - HDP_2.5_virtualbox). I killed the jobs with putty as root : yarn application -kill application_1482410373661_0002 but they are still visible on Ambari. [root@sandbox ~]# yarn application -kill application_1482410373661_0002 16/12/24 12:26:40 INFO impl.TimelineClientImpl: Timeline service address: http://sandbox.hortonworks.com:8188/ws/v1/timeline/ 16/12/24 12:26:40 INFO client.RMProxy: Connecting to ResourceManager at sandbox.hortonworks.com/172.17.0.2:8050 16/12/24 12:26:40 INFO client.AHSProxy: Connecting to Application History server at sandbox.hortonworks.com/172.17.0.2:10200 16/12/24 12:26:44 WARN retry.RetryInvocationHandler: Exception while invoking ApplicationClientProtocolPBClientImpl.getApplicationReport over null.

I've found an issue corresponding : Tez client keeps trying to talk to RM even if RM does not know about the application https://issues.apache.org/jira/browse/TEZ-3156 This patch should be included as it was fixed for version 0.7.1 In the log (Ambary query) I can read 993 time : INFO : Map 1: 0/1 Reducer 2: 0/2 The query is the proposed in the tutorial : ( http://fr.hortonworks.com/hadoop-tutorial/hello-world-an-introduction-to-hadoop-hcatalog-hive-and-pig/#section_4) <code>SELECT truckid, avg(mpg) avgmpg FROM truck_mileage GROUP BY truckid; Any idea how to clear the history and restart without the running state ?
