Subject [jira] [Created] (HADOOP-7818) DiskChecker#checkDir should fail if the directory is not executable

DiskChecker#checkDir should fail if the directory is not executable
-------------------------------------------------------------------

                 Key: HADOOP-7818
                 URL: https://issues.apache.org/jira/browse/HADOOP-7818
             Project: Hadoop Common
          Issue Type: Bug
          Components: util
    Affects Versions: 0.20.205.0, 0.23.0, 0.24.0
            Reporter: Eli Collins
            Assignee: Eli Collins
            Priority: Minor


DiskChecker#checkDir fails if a directory can't be created, read, or written but does not
fail if the directory exists and is not executable. This causes subsequent code to think the
directory is OK but later fail due to an inability to access the directory (eg see MAPREDUCE-2921).
I propose checkDir fails if the directory is not executable. Looking at the uses, this should
be fine, I think it was ignored because checkDir is often used to create directories and it
creates executable directories.
