Description

The framework uploader tool has this piece of code which makes sure that all block of the uploaded mapreduce tarball has been replicated:

      while(endTime - startTime < timeout * 1000 &&
           currentReplication < acceptableReplication) {
        Thread.sleep(1000);
        endTime = System.currentTimeMillis();
        currentReplication = getSmallestReplicatedBlockCount();
      }

There are cases, however, when we don't want to wait for this (eg. we want to speed up Hadoop installation).

I suggest adding --skiprelicationcheck switch which disables this replication test.
