Kezhu Wang created FLINK-12491: ---------------------------------- Summary: Incorrect documentation for directory path separators of CoreOptions.TMP_DIRS Key: FLINK-12491 URL: https://issues.apache.org/jira/browse/FLINK-12491 Project: Flink Issue Type: Improvement Components: Runtime / Configuration Affects Versions: 1.8.0, 1.7.2, 1.6.4, 1.9.0 Reporter: Kezhu Wang Assignee: Kezhu Wang
{{CoreOptions.TMP_DIRS}} and {{ConfigConstants.TASK_MANAGER_TMP_DIR_KEY}} both say that: {quote} The config parameter defining the directories for temporary files, separated by * ",", "|", or the system's \{@link java.io.File#pathSeparator}. {quote} But the parsing phase uses {{String.split}} with argument {{",|" + File.pathSeparator}} eventually. However, in fact the sole parameter of {{String.split}} is a regular expression, so the directory path separators are "," or {{java.io.File#pathSeparator}}. After digging into history, I found that the documentation was introduced in commit {{a7c407ace4f6cbfbde3e247071cee5a755ae66db}} and inherited by {{76abcaa55d0d6ab704b7ab8164718e8e2dcae2c4}}. So, I think it is safe to drop "|" from documentation. {code:title=ConfigurationUtils.java} public class ConfigurationUtils { private static String[] splitPaths(@Nonnull String separatedPaths) { return separatedPaths.length() > 0 ? separatedPaths.split(",|" + File.pathSeparator) : EMPTY; } {code} -- This message was sent by Atlassian JIRA (v7.6.3#76005)
