Dear Cloudera community   I'm struggling to get Hive jobs to run on Tez on our kerberized cluster with HA RM.  We're getting the following error, does anyone have any idea what the problem is?   Kind regards Michael       2021-07-19 16:51:41,744 [INFO] [ServiceThread:org.apache.tez.dag.app.web.WebUIService] |http.HttpServer2|: Added global filter 'safety' (class=org.apache.hadoop.http.HttpServer2$QuotingInputFilter) 2021-07-19 16:51:41,787 [ERROR] [ServiceThread:org.apache.tez.dag.app.web.WebUIService] |web.WebUIService|: Tez UI WebService failed to start. java.lang.NullPointerException at org.apache.hadoop.util.StringUtils.join(StringUtils.java:941) at org.apache.hadoop.yarn.server.webproxy.amfilter.AmFilterInitializer.initFilter(AmFilterInitializer.java:74) at org.apache.hadoop.http.HttpServer2.initializeWebServer(HttpServer2.java:587) at org.apache.hadoop.http.HttpServer2.<init>(HttpServer2.java:537) at org.apache.hadoop.http.HttpServer2.<init>(HttpServer2.java:117) at org.apache.hadoop.http.HttpServer2$Builder.build(HttpServer2.java:421) at org.apache.hadoop.yarn.webapp.WebApps$Builder.build(WebApps.java:340) at org.apache.hadoop.yarn.webapp.WebApps$Builder.start(WebApps.java:427) at org.apache.tez.dag.app.web.WebUIService.serviceStart(WebUIService.java:94) at org.apache.hadoop.service.AbstractService.start(AbstractService.java:194) at org.apache.tez.dag.app.DAGAppMaster$ServiceWithDependency.start(DAGAppMaster.java:1865) at org.apache.tez.dag.app.DAGAppMaster$ServiceThread.run(DAGAppMaster.java:1886)     ...

Hi   We are periodically getting errors in our resource manager logs, which then cause no Spark jobs to be accepted until we restart the YARN ResourceManager. We are on HDP 3.1.4 and we have Kerberos enabled.    The stack trace is below. Does anyone have ideas, please?         2021-05-08 04:15:59,407 ERROR yarn.YarnUncaughtExceptionHandler (YarnUncaughtExceptionHandler.java:uncaughtException(68)) - Thread Thread[Thread-20,5,main] threw an Exception. java.lang.NullPointerException at org.apache.hadoop.yarn.server.resourcemanager.scheduler.common.ResourceCommitRequest.<init>(ResourceCommitRequest.java:101) at org.apache.hadoop.yarn.server.resourcemanager.scheduler.capacity.CapacityScheduler.createResourceCommitRequest(CapacityScheduler.java:2848) at org.apache.hadoop.yarn.server.resourcemanager.scheduler.capacity.CapacityScheduler.submitResourceCommitRequest(CapacityScheduler.java:2685) at org.apache.hadoop.yarn.server.resourcemanager.scheduler.capacity.CapacityScheduler.allocateContainerOnSingleNode(CapacityScheduler.java:1558) at org.apache.hadoop.yarn.server.resourcemanager.scheduler.capacity.CapacityScheduler.allocateContainersToNode(CapacityScheduler.java:1684) at org.apache.hadoop.yarn.server.resourcemanager.scheduler.capacity.CapacityScheduler.allocateContainersToNode(CapacityScheduler.java:1436) at org.apache.hadoop.yarn.server.resourcemanager.scheduler.capacity.CapacityScheduler.schedule(CapacityScheduler.java:548) at org.apache.hadoop.yarn.server.resourcemanager.scheduler.capacity.CapacityScheduler$AsyncScheduleThread.run(CapacityScheduler.java:595)       ...

Out of curiosity, why is R/SparkR only provided through Livy in HDP 2.5 as it is provided as standard with the standalone Zeppelin package? Thanks. ... View more
