Examples of org.apache.hadoop.fs.permission.AclStatus

org.apache.hadoop.fs.permission.AclStatus
An AclStatus contains the ACL information of a specific file. AclStatus instances are immutable. Use a {@link Builder} to create a new instance.

      aclEntry(DEFAULT, USER, ALL),
      aclEntry(DEFAULT, USER, "foo", ALL),
      aclEntry(DEFAULT, GROUP, READ_EXECUTE),
      aclEntry(DEFAULT, MASK, ALL),
      aclEntry(DEFAULT, OTHER, NONE) };
    AclStatus s = fs.getAclStatus(dirPath);
    AclEntry[] returned = s.getEntries().toArray(new AclEntry[0]);
    assertArrayEquals(expected, returned);
    assertPermission(dirPath, (short)010750);
    assertAclFeature(dirPath, true);
    expected = new AclEntry[] { };
    s = fs.getAclStatus(linkPath);
    returned = s.getEntries().toArray(new AclEntry[0]);
    assertArrayEquals(expected, returned);
    assertPermission(linkPath, (short)0640);
    assertAclFeature(linkPath, false);
    s = fs.getAclStatus(filePath);
    returned = s.getEntries().toArray(new AclEntry[0]);
    assertArrayEquals(expected, returned);
