flink 1.7.2 YARN Session模式提交任务问题求助
大家好
目前环境是flink 1.7.2，使用YARN Session模式提交任务，Hadoop 版本2.7.3，hdfs namenode配置了ha模式，提交任务的时候报以下错误，系统环境变量中已经设置了HADOOP_HOME,YARN_CONF_DIR，HADOOP_CONF_DIR，HADOOP_CLASSPATH，在flink_conf.yaml中配置了fs.hdfs.hadoopconf

这个hdfsClusterForML是namenode ha 的nameservice，经过分析是没加载hdfs-site.xml配置导致的，
也尝试过把Hadoop的几个配置文件放到flink 的conf目录下但都无效，最终通过改YarnResourceManager源码后能够正常提交任务。
public YarnResourceManager(
RpcService rpcService,
String resourceManagerEndpointId,
ResourceID resourceId,
Configuration flinkConfig,
Map<String, String> env,
HighAvailabilityServices highAvailabilityServices,
HeartbeatServices heartbeatServices,
SlotManager slotManager,
MetricRegistry metricRegistry,
JobLeaderIdService jobLeaderIdService,
ClusterInformation clusterInformation,
FatalErrorHandler fatalErrorHandler,
@Nullable String webInterfaceUrl,
JobManagerMetricGroup jobManagerMetricGroup) {
super(
rpcService,
resourceManagerEndpointId,
resourceId,
highAvailabilityServices,
heartbeatServices,
slotManager,
metricRegistry,
jobLeaderIdService,
clusterInformation,
fatalErrorHandler,
jobManagerMetricGroup);
this.flinkConfig = flinkConfig;
this.yarnConfig = new YarnConfiguration(HadoopUtils.getHadoopConfiguration(flinkConfig));
但我认为这肯定不是解决这个问题的方法，所以向大家求助，是不是我忽略什么。
