[jira] Updated: (HADOOP-6377) ChecksumFileSystem.getContentSummary throws NPE when directory contains inaccessible directories

     [ https://issues.apache.org/jira/browse/HADOOP-6377?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Todd Lipcon updated HADOOP-6377:
--------------------------------

    Description: When getContentSummary is called on a path that contains an unreadable directory, it throws NPE, since RawLocalFileSystem.listStatus(Path) returns null when File.list() returns null.  (was: There seems to be some inconsistent usage of "null" vs empty arrays in FileSystem that causes NPEs trying to getContentSummary of a path directly within the root.)
        Summary: ChecksumFileSystem.getContentSummary throws NPE when directory contains inaccessible directories  (was: ChecksumFileSystem.getContentSummary throws NPE on /foo)
