yarn rmadmin -getallservicestate

Yarn问题

常用的命令
1、 yarn rmadmin -getServiceState rm1 查看active或者是standby状态

2、手动切换主备
yarn rmadmin -transitionToStandby rm2 --forcemanual 将rm2主切换成备
yarn rmadmin -transitionToActive rm1 --forcemanual 将rm1备切换成主
yarn rmadmin -getServiceState rm1

1、yarn假死状态，日志一直刷新以下信息：log aggregation have not finished yet

Max number of completed apps kept in state store met: maxCompletedAppsInStateStore = 10000, but not removing app application_1618886060273_3657 from state store as log aggregation have not finished yet

yarn的BUG：https://issues.apache.org/jira/browse/YARN-4946

修复步骤是先处理standby RM，再处理active RM，RM节点替换步骤是：
（1） mv方式备份旧包： mv $HADOOP_HOME/share/hadoop/yarn/hadoop-yarn-server-resourcemanager-$version.jar <备份路径>
（2）copy新包 ,下载高于3.2.0版本hadoop-yarn-server-resourcemanager-$version.jar包
（3）重启RM

2、yarn-labels

先yarn-site配置

yarn.node-labels.enabled=true
yarn.node-labels.fs-store.root-dir=hdfs://namenode:port/path/node-labels/
1
2

再master节点执行：

##添加标签
 yarn rmadmin -addToClusterNodeLabels "label_1(exclusive=true/false),label_2(exclusive=true/false)" 
## exclusive 默认（true）
##查看标签
 yarn cluster --list-node-labels
##删除YARN Node Labels
yarn rmadmin -removeFromClusterNodeLabels "<label>[,<label>,...]"
##增加/修改标签映射
yarn rmadmin -replaceLabelsOnNode “node1[:port]=label1 node2=label2” [-failOnUnknownNodes]
 ##node1的地址需要到yarn页面看nodes查看

4.yarn队列提交显示队列不存在

用户有个root.etl.streaming的队列，但是使用使用queue=root.etl.streaming报错没有队列，使用queue=etl.streaming也报错没有队列
解决办法：queue指定队列只需要指定最后的队列名，所以queue=streaming后成功

5、用户提交作业一直ACCEPTED状态

1）发现ACCEPTED作业的描述信息中有如下日志：

yarn.scheduler.capacity.maximum-am-resource-percent默认0.25可以适当调大

2）还有一种是对应的队列满了，比如下面情况：
一共34000，已经使用了32768，用户提交任务一种处于ACCEPTED

调大队列的大小~
3）用户有2个队列，default队列分配75%的资源，但是设置最大资源是100%，当使用到75%时任务处于ACCEPTED

原因时yarn.scheduler.capacity.root.default.user-limit-factor参数默认时1，标识一个用户只能使用队列分配的最大值75%，当yarn.scheduler.capacity.root.default.user-limit-factor设置成2时，就可以继续提交到空闲内存
，或者换一个用户提交作业也可以提交到空闲内存

6、用户设置队列acl的提交权限，但是不生效

必须对root设置权限

7、yarn节点下线后再添加回去

1、修改去除已下线节点的地址/etc/ecm/hadoop-conf/yarn.exclude
2、header节点执行 yarn rmadmin -refreshNodes
3、emr控制台启动nm

8、curl http://hadoop:8088/cluster 显示没权限

新版本hadoop.http.authentication.simple.anonymous.allowed这个值为false导致访问yarn页面的时候要加上?user.name=xxxxxx，否则没有权限
或者打开权限hadoop.http.authentication.simple.anonymous.allowed改为true，然后重启yarn

9、emr集群重启后2个rm全都standby

问题描述：用户重启rm后2个rm都是standby状态，

先使用hadoop用户执行命令yarn rmadmin -transitionToActive rm1 --forcemanual强制rm1切换成active，但是不成功
看报错信息是zk出现问题，但是使用zkCli.sh是没有问题的，开源资料查询需要调大
“-Djute.maxbuffer=10000000”
逐个重启zk，先启动follower
还是报错，在yarn的环境也添加上/var/lib/ecm-agent/cache/ecm/service/YARN/x.x.x.x.x/package/templates 里找到yarn-env.sh YARN_OPTS = “-Djute.maxbuffer=10000000”
重启yarn，还是报错

使用命令yarn resourcemanager -format-state-store格式化rm的状态存储，

还是报错，只能手动去zk删除对应的任务znode状态
deleteall /rmstore/ZKRMStateRoot/RMAppRoot/application_ 1595251161356_11443
删除后成功
解决办法：作业触发了 ResourceManager zk的异常，修复zk 问题以后重启RM 卡在了一个异常作业上1595251161356_11443，这个情况下，可以清理zk store快速恢复，但是有个异常，所以手动清理了异常作业的zk信息

10、spark on yarn 显示提交作业的vcore数量和参数提交的对不上

yarn.scheduler.capacity.resource-calculator org.apache.hadoop.yarn.util.resource.DefaultResourceCalculator 改成：org.apache.hadoop.yarn.util.resource.DominantResourceCalculator

11、yarn查看日志报错：User [dr.who] is not authorized to view the logs for container_1623238721588_0301_02_000001 in log file

原因是开启了acl的权限
