Hi David Thanks for your answers. I have few questions too ,
*What will happen if datanode1 restarted while sending segments to datanode2* 1. On datanode1 start-up, which will be become primary shard ? Shard in datanode1 or shard in datanode2 ? 2. If datanode1 becomes primary then how would it knows , how many amount of segments are transferred to datanode2 before restart happen? 3. if datanode2 becomes primary , what will happen to already written segments (very earlier - pending segments to be copied) ?
