*大家好, *
*我正在测试在k8s集群部署模式下使用HA架构的HDFS集群, 以下是我的提交命令参数*
./bin/flink run-application \
--detached \
--target kubernetes-application \
-Dkubernetes.cluster-id=test \
-Dkubernetes.container.image=flink-java11 \
-Dfs.default-scheme=hdfs://datacluster \
-Dkubernetes.rest-service.exposed.type=LoadBalancer \
-Dhigh-availability=org.apache.flink.kubernetes.highavailability.KubernetesHaServicesFactory
\
-Dhigh-availability.storageDir=hdfs://datacluster/flink/recovery \
-Dkubernetes.namespace=flink \
-Dkubernetes.service-account=flink-sa \
-Denv.hadoop.conf.dir=/opt/flink/conf \
-Dkubernetes.container.image.pull-policy=Always \
local:///opt/flink/usrlib/test.jar
*我已经复制了core-site.xml 和hdfs-site.xml到$FLINK_HOME/conf下, 目录结构如下*
flink@e3187a41a139:~$ ls conf
core-site.xml hdfs-site.xml log4j-console.properties
log4j-session.properties logback-session.xml masters zoo.cfg
flink-conf.yaml log4j-cli.properties log4j.properties logback-console.xml
logback.xml workers
*但是遇到了下面的报错:*

*我尝试把以下提交的格式更换为active的namenode节点可以正常提交并运行,*
-Dfs.default-scheme=hdfs://namenode-active:8020 \
-Dhigh-availability.storageDir=hdfs://namenode-active:8020/flink/recovery \
所以还无法明白我是哪里搞错了, 是不是flink不支持HA架构的hdfs集群, 望解惑, 非常感谢!
*补充信息:*
hadoop版本: 3.3.4
flink版本: 1.15.2
*hadoop hdfs-site.xml相关配置如下*
