The comment on the change is:
change wording to avoid text being interpreted as Wiki words

  == Assertions ==
  
-  * All hbase data and state is out on the FileSystem: Moving from one version should be
just a case of moving or rewriting files on the FileSystem.
+  * All hbase data and state is out on the file system: Moving from one version should be
just a case of moving or rewriting files on the file system.
   * Hbase cannot be running when a migration is run.
    * This can be tricky to assert when the hbase versions differ to the extent that they
are unable to talk to each other (Caller just hangs and eventually timesout).
   * Sometimes, the amount of on-filesystem data that needs to be changed will be large so
migration will need to run a MR job.
