Kuhu Shukla created TEZ-3345:
--------------------------------
Summary: Diagnostics for a failed AM may not show up on the DAG UI
page.
Key: TEZ-3345
URL: https://issues.apache.org/jira/browse/TEZ-3345
Project: Apache Tez
Issue Type: Bug
Components: UI
Reporter: Kuhu Shukla
In a scenario where AM fails on all its attempts, the DAG page does not show
the Diagnostics message on the Tez UI "Diagnostics" section. The messageis
available on the AHS and could be pulled into the DAG page just like we do for
failed vertices.
I ran a simple Tez example job that was given way too less memory causing the
AM to fail:
{code}
hadoop jar /home/gs/tez/current/tez-examples-0.7.1.x.x.jar orderedwordcount
-Dtez.am.resource.memory.mb=16 -Dtez.am.launch.cmd-opts="-Xmx13m
-Djava.net.preferIPv4Stack=true -XX:+UseNUMA -XX:+PrintGCDetails
-XX:+PrintGCDateStamps -Xloggc:<LOG_DIR>/gc.log"/books /output
{code}
