本文解决Ambari系统中出现的Unhealthy告警问题，具体表现为Nodemanager未挂掉但所有MapReduce任务无法执行。通过调整yarn-site.xml中的磁盘健康检查配置参数，或清理磁盘空间来解决因磁盘空间不足导致的任务阻塞。

Unhealthy Node local-dirs and log-dirs are bad”

ambari的系统里出现这个告警，但是nodemanager也没有挂掉，所有的mapreduce任务都不能进行，处于卡主状态，有的日志还出现这个

yarn all application 中显示任务已经accept，但是没有执行，没有分配job url，原因就是磁盘的空间太满了，跟yarn-site.xml中的以下配置有关

<property>
        <name>yarn.nodemanager.disk-health-checker.max-disk-utilization-per-disk-percentage</name>
        <value>98.5</value>
</property>

try adding the property yarn.nodemanager.disk-health-checker.max-disk-utilization-per-disk-percentage to yarn-site.xml. This property specifies the maximum percentage of disk space utilization allowed after which a disk is marked as bad. Values can range from 0.0 to 100.0.

你可以清理磁盘空间，或者你可以暂时的吧这个使用率调大，但是这不是解决问题的根本，最好是清理磁盘空间或扩展
