   Hi @kaijianding , sorry for late response. I just change the strategy for lazyOnStart action as you suggested.
   I build a new CallBack action `() -> this.removeSegment(segment, DataSegmentChangeCallback.NOOP, false)`. When query failed caused by lazyOnStart, this action will unload this segment and let the coordinator choose another historical to load. And I have tested it on dev cluster and works fine. Could you please help review the code? Thanks.
