      Here's what I did:
      -Setup a 2 node cluster (10.1.5.7, 10.1.5.8)
      -Run this command line to add 2 more nodes (10.1.5.9, 10.1.3.100) and remove
      the original 2 at the same time:
      /opt/membase/bin/cli/membase rebalance -c 10.1.5.7 -u Administrator -p norths
      --server-add=10.1.5.9 --server-add=10.1.3.100 --server-remove=10.1.5.7
      --server-remove=10.1.5.8

      This says it completed successfully but when I went into 10.1.5.9 it showed
      that 10.1.5.8 was still on the pending rebalance list. I clicked rebalance via
      the UI and it's now stuck at 0%.

      Diag from the three nodes stuck in rebalancing attached.
