      Description

      This bug is non-fatal in versions earlier than 3.1.2 (i.e., prior to the changes in SERVER-15207).

      It requires the mapReduce to be performed on a special collection like "admin.system.roles" or "admin.system.users".

      3.1.2+:

       W ACCESS   [repl writer worker 15] Skipping bad update to roles collection in oplog. NoSuchKey Missing expected field "role" Oplog entry: i
       W ACCESS   [repl writer worker 15] Skipping bad update to roles collection in oplog. NoSuchKey Missing expected field "role" Oplog entry: i
       E REPL     [repl writer worker 15] Failed command { create: "tmp.mr.system.roles_0", temp: true } on admin with status BadValue cannot write to 'admin.tmp.mr.system.roles_0' during oplog application
       I -        [repl writer worker 15] Fatal Assertion 16359
      

      3.1.1 and 3.0.4:

      W ACCESS   [repl writer worker 15] Skipping bad update to roles collection in oplog. NoSuchKey Missing expected field "role" Oplog entry: i
      W REPL     [repl writer worker 15] Failed command { create: "tmp.mr.system.roles_0", temp: true } on admin with status BadValue cannot write to 'admin.tmp.mr.system.roles_0' during oplog application
      I COMMAND  [repl writer worker 15] CMD: drop admin.tmp.mr.system.roles_0
      W REPL     [repl writer worker 15] Failed command { drop: "tmp.mr.system.roles_0" } on admin with status UnknownError ns not found during oplog application
