我们有ambari和hadoop（HDP 2.6.4）集群
在ambari中，我们有ambari-metrics-collector
指标收集器有时会崩溃，我们可以从日志中看到以下
请注意-这在配置embedded和distributed上都会发生

不清楚我们为什么得到
2019-11-26 00:57:20,690 WARN org.apache.hadoop.yarn.webapp.GenericExceptionHandler: INTERNAL_SERVER_ERROR
我必须说，我们根据-https://cwiki.apache.org/confluence/display/AMBARI/Configurations+-+Tuning
调整了指标收集器参数所以我们不明白为什么ambari指标收集器失败
具有ambari指标收集器的计算机包括以下rpm
ambari-metrics-monitor-2.6.2.2-1.x86_64
ambari-metrics-common-2.6.2.2-1.noarch
ambari-agent-2.6.2.2-1.x86_64
