We recently upgraded to YARN with CDH 5.
(Version: 2.3.0 cdh5.1.3, r8e266e052e423af592871e2dfe09d54c03f6a0e8)
I tried to access the logs of a failed job from the resource manager by clicking the logs on ApplicationMaster, but received the following error:
Failed to redirect container_1412602970010_0037_01_000002 Container failed while trying to create a redirect URL for the log server. Log The server URL may not be configured. The container does not exist.
Also in the pig/mapreduce job, we see the following warnings:
INFO: 2014-10-07 15: 42: 19,134 [main] WARN org.apache.hadoop.security.UserGroupInformation - PriviledgedActionException as: jobs (auth: SIMPLE) call: java.io.IOException: org.apache.hadoop.ipc .RemoteException (org.apache.hadoop.yarn.exceptions.YarnRuntimeException): Failed to load HDFS history file: // prod-Hadoop: 8020 / user / history / done_intermediate / Job / job_1412706451566_0032-1412710613932-workers-PigLatin% 3Aclk_im__j___j % 2D04T13-1412710831122-14-2-SUCCEEDED-root.jobs-1412710694546.jhist>
Am I missing anything in the configuration?
