----------------------------------

             Summary: different service on the same machine would make the shared audit local buffer directory access confilct when using hdfs to store audit log
                 Key: RANGER-1368
                 URL: https://issues.apache.org/jira/browse/RANGER-1368
             Project: Ranger
          Issue Type: Bug
          Components: audit
    Affects Versions: 0.6.0, 0.7.0
         Environment: linux centos 6,ranger 0.6.0
            Reporter: zhangxiong


when configured hdfs to store ranger audit log, different service on the same machine would make the shared audit local buffer directory access confilct.
detail:
suppose that we have a server S with one hdfs NameNode NN and yarn ResourceManager RM deployed on it, and ranger configured hdfs as audit log storage backend and configured a local log buffer directory /tmp/ranger/log/ via 'xasecure.audit.hdfs.config.local.buffer.directory' .
first ,namenode started and find the directory /tmp/ranger/log/ doesn't exists, so NN created the dir with access mod 700 and continues its own work . then resourcemanager started and need to store its audit log to the already exist dir ,unfortunately RM has no access authz to the dir and cannot work well.
