### Description of PR When RM starts, because the file corresponding to the `yarn.resourcemanager.nodes.include-path` or `yarn.resourcemanager.nodes.exclude-path` configuration item does not exist, it will disable this function. https://github.com/apache/hadoop/blob/405ed1dde6bcccca1e07e45a356a89c1b583e236/hadoop-yarn-project/hadoop-yarn/hadoop-yarn-server/hadoop-yarn-server-resourcemanager/src/main/java/org/apache/hadoop/yarn/server/resourcemanager/NodesListManager.java#L552-L570 But in RM failover scenario, because the file does not exist, it will fail. ```java Caused by: org.apache.hadoop.ha.ServiceFailedException: RefreshAll operation failed at org.apache.hadoop.yarn.server.resourcemanager.AdminService.refreshAll(AdminService.java:788) at org.apache.hadoop.yarn.server.resourcemanager.AdminService.transitionToActive(AdminService.java:315) ... 29 more Caused by: java.nio.file.NoSuchFileException: /tmp/non-existent-path-788aa744-1395-40ca-bdb5-f93bffc92cfb at sun.nio.fs.UnixException.translateToIOException(UnixException.java:86) at sun.nio.fs.UnixException.rethrowAsIOException(UnixException.java:102) at sun.nio.fs.UnixException.rethrowAsIOException(UnixException.java:107) at sun.nio.fs.UnixFileSystemProvider.newByteChannel(UnixFileSystemProvider.java:214) at java.nio.file.Files.newByteChannel(Files.java:361) at java.nio.file.Files.newByteChannel(Files.java:407) at java.nio.file.spi.FileSystemProvider.newInputStream(FileSystemProvider.java:384) at java.nio.file.Files.newInputStream(Files.java:152) at org.apache.hadoop.util.HostsFileReader.readFileToMap(HostsFileReader.java:126) at org.apache.hadoop.util.HostsFileReader.refreshInternal(HostsFileReader.java:214) at org.apache.hadoop.util.HostsFileReader.refresh(HostsFileReader.java:192) at org.apache.hadoop.yarn.server.resourcemanager.NodesListManager.refreshHostsReader(NodesListManager.java:258) at org.apache.hadoop.yarn.server.resourcemanager.NodesListManager.refreshNodes(NodesListManager.java:232) at org.apache.hadoop.yarn.server.resourcemanager.NodesListManager.refreshNodes(NodesListManager.java:224) at org.apache.hadoop.yarn.server.resourcemanager.AdminService.refreshNodes(AdminService.java:490) at org.apache.hadoop.yarn.server.resourcemanager.AdminService.refreshAll(AdminService.java:778) ``` ### How was this patch tested? add UT ### For code changes: - [ ] Does the title or this PR starts with the corresponding JIRA issue id (e.g. 'HADOOP-17799.
