John Zhuge commented on HADOOP-7352: ------------------------------------ Globber has its own version of {{listStatus}} which converts IOE to empty array: {code} private FileStatus[] listStatus(Path path) throws IOException { try { if (fs != null) { return fs.listStatus(path); } else { return fc.util().listStatus(path); } } catch (IOException e) { return new FileStatus[0]; } } {code} > FileSystem#listStatus should throw IOE upon access error > -------------------------------------------------------- > > Key: HADOOP-7352 > URL: https://issues.apache.org/jira/browse/HADOOP-7352 > Project: Hadoop Common > Issue Type: Improvement > Components: fs > Affects Versions: 2.6.0 > Reporter: Matt Foley > Assignee: John Zhuge > Attachments: HADOOP-7352.001.patch > > > In HADOOP-6201 and HDFS-538 it was agreed that FileSystem::listStatus should > throw FileNotFoundException instead of returning null, when the target > directory did not exist. > However, in LocalFileSystem implementation today, FileSystem::listStatus > still may return null, when the target directory exists but does not grant > read permission. This causes NPE in many callers, for all the reasons cited > in HADOOP-6201 and HDFS-538. See HADOOP-7327 and its linked issues for > examples. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: common-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: common-issues-h...@hadoop.apache.org
