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 "local-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.
{color:#d04437}*But I still strongly recommend adding error log messages for
unhealthy nodemanger(especially for startup).*{color}
