Chris Nauroth created HADOOP-9767: ------------------------------------- Summary: RawLocalFileSystem#rename does not correctly enforce replacement of empty destination directory on all platforms Key: HADOOP-9767 URL: https://issues.apache.org/jira/browse/HADOOP-9767 Project: Hadoop Common Issue Type: Bug Components: fs Affects Versions: 3.0.0, 1-win, 2.1.0-beta, 1.3.0 Reporter: Chris Nauroth Assignee: Chris Nauroth
POSIX {{rename}} semantics state that renaming a source directory to an existing destination directory that is empty will act as a full replacement of that existing destination. {{RawLocalFileSystem#rename}} calls Java's {{File#renameTo}}, which provides these semantics on most platforms. On some platforms (notably Windows), {{File#renameTo}} does not provide this behavior. This causes problems for MapReduce and other downstream components like Hive, HCatalog, and Sqoop that depend on the replacement behavior. -- This message is automatically generated by JIRA.
