lujie updated YARN-8381:
------------------------
Description:
I started a fresh pseudo-distributed system on an node, then run a job but it
stuck. My first reaction was checking log message to local problem, but
obtaining no error message.
After reading log messages for long time, I waked up to check the node health
. The Yarn web UI showed that the nodemanager is unhealthy, due to the
"l\{{ocal-dirs are bad: /tmp/hadoop-hduser/nm-local-dir}}". I reconfigure the
"{{yarn.nodemanager.disk-health-checker.max-disk-utilization-per-disk-percentage}}"
to 98% and solved this problem. But I still strongly recommend adding error
log messages for unhealthy nodemanger.
