Hint delivery fails when prefer_local enabled

      Description

      I tried to decommission one node.
      Node sent all data to another node and got stuck in LEAVING state.
      Log message shows Exception in HintsDispatcher thread.
      Could it be reason of stuck in LEAVING state?

      command output:

      root@cas-node6:~# time nodetool decommission
