Chris Nauroth commented on HADOOP-9413: --------------------------------------- Bikas, the best explanation of the issue mentioned by Ivan is in his latest patch, in the comments for {{FileUtil#setExecutable}}. I've pasted that comment below. More details are discussed in HADOOP-9525, within the preliminary patch that Ivan provided for adding more tests of chmod on Windows. {code} + /** + * Platform independent implementation for {@link File#setExecutable(boolean)} + * File#setExecutable does not work as expected on Windows. + * Note: revoking execute permission on folders does not have the same + * behavior on Windows as on Unix platforms. Creating, deleting or renaming + * a file within that folder will still succeed on Windows. + * @param f input file + * @param executable + * @return true on success, false otherwise + */ + public static boolean setExecutable(File f, boolean executable) { {code} > Introduce common utils for File#setReadable/Writable/Executable and > File#canRead/Write/Execute that work cross-platform > ----------------------------------------------------------------------------------------------------------------------- > > Key: HADOOP-9413 > URL: https://issues.apache.org/jira/browse/HADOOP-9413 > Project: Hadoop Common > Issue Type: Bug > Reporter: Ivan Mitic > Assignee: Ivan Mitic > Fix For: 3.0.0 > > Attachments: HADOOP-9413.commonfileutils.2.patch, > HADOOP-9413.commonfileutils.3.patch, HADOOP-9413.commonfileutils.4.patch, > HADOOP-9413.commonfileutils.5.patch, HADOOP-9413.commonfileutils.patch > > > So far, we've seen many unittest and product bugs in Hadoop on Windows > because Java's APIs that manipulate with permissions do not work as expected. > We've addressed many of these problems on one-by-one basis (by either > changing code a bit or disabling the test). While debugging the remaining > unittest failures we continue to run into the same patterns of problems, and > instead of addressing them one-by-one, I propose that we expose a set of > equivalent wrapper APIs that will work well for all platforms. > Scanning thru the codebase, this will actually be a simple change as there > are very few places that use File#setReadable/Writable/Executable and > File#canRead/Write/Execute (5 files in Common, 9 files in HDFS). > HADOOP-8973 contains additional context on the problem. -- This message is automatically generated by JIRA.
