Update documentation Hadoop Groups Mapping to add static group mapping, negative cache

    Details

      Description

      After Hadoop Group Mapping was written, I subsequently found a number of other things that should be added/updated:

      1. static group mapping, statically map users to group names (HADOOP-10142)
      2. negative cache, to avoid spamming NameNode with invalid user names (HADOOP-10755)
      3. update query pattern for LDAP groups mapping if posix semantics is supported. (HADOOP-9477)
