need translate java.nio.file.NoSuchFileException to FileNotFoundException in DeprecatedRawLocalFileStatus constructor. HADOOP-12045 adds nio to support access time, but nio will create java.nio.file.NoSuchFileException instead of FileNotFoundException. many hadoop codes depend on FileNotFoundException to decide whether a file exists. for example {{FileContext.util().exists()}}. {code} public boolean exists(final Path f) throws AccessControlException, UnsupportedFileSystemException, IOException { try { FileStatus fs = FileContext.this.getFileStatus(f); assert fs != null; return true; } catch (FileNotFoundException e) { return false; } } {code} same for {{FileSystem#exists}} {code} public boolean exists(Path f) throws IOException { try { return getFileStatus(f) != null; } catch (FileNotFoundException e) { return false; } } {code} NoSuchFileException will break these functions. Several test failures are caused by this issue: https://builds.apache.org/job/PreCommit-YARN-Build/8630/testReport/org.apache.hadoop.yarn.server.nodemanager/TestDeletionService/testRelativeDelete/ https://builds.apache.org/job/PreCommit-YARN-Build/8632/testReport/org.apache.hadoop.yarn.server.nodemanager/TestDeletionService/testAbsDelete/ -- This message was sent by Atlassian JIRA (v6.3.4#6332)
