?Hi Udit,
Do you have full exception stack? Perhaps you have run into the same issue: YARN-3393. ?

I have also enabled resource manager HA due to which the timeline server seems to fail everytime there is a failover. Is this a known issue or am I doing something wrong? I am unable to access the servlet "/applicationHistory" on the timeline server and these are the logs I see: 2015-04-23 18:20:55,380 ERROR webapp.View (AppsBlock.java:render(90)) - Failed to read the applications. java.lang.reflect.UndeclaredThrowableException at org.apache.hadoop.security.UserGroupInformation.doAs(UserGroupInformation.java:1643) at org.apache.hadoop.yarn.server.webapp.AppsBlock.render(AppsBlock.java:80) at org.apache.hadoop.yarn.webapp.view.HtmlBlock.render(HtmlBlock.java:67) Does anyone know what could be the issue? Thanks, Udit
