Chris Nauroth resolved HADOOP-4109. ----------------------------------- Resolution: Duplicate Truncate has been implemented, tracked in HDFS-3107. > FileSystem support for posix truncate method > -------------------------------------------- > > Key: HADOOP-4109 > URL: https://issues.apache.org/jira/browse/HADOOP-4109 > Project: Hadoop Common > Issue Type: New Feature > Components: fs > Reporter: Pete Wyckoff > > {code} > void truncate(Path path, long offset) throws IOException; > {code} > from man truncate: > DESCRIPTION > The truncate and ftruncate functions cause the regular file named by > path or referenced by fd to be truncated to a size of precisely length bytes. > If the file previously was larger than this size, the extra data is > lost. If the file previously was shorter, it is extended, and the extended > part reads as zero bytes. > The file pointer is not changed. > If the size changed, then the ctime and mtime fields for the file are > updated, and suid and sgid mode bits may be cleared. > With ftruncate, the file must be open for writing; with truncate, the > file must be writable. > RETURN VALUE > On success, zero is returned. On error, -1 is returned, and errno is > set appropriately. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: common-dev-unsubscr...@hadoop.apache.org For additional commands, e-mail: common-dev-h...@hadoop.apache.org
