可以指定多个数据路径，以便跨多个磁盘或位置传播数据，但是来自单个分片的所有文件都将写入同一路径。官网解读：
Multiple data paths may be specified, in order to spread data across multiple disks or locations, but all of the files from a single shard will be written to the same path. This can be configured as follows:Multiple data paths may be specified, in order to spread data across multiple disks or locations, but all of the files from a single shard will be written to the same path.
This can be configured as follows:
--------------------------------- path.data: /mnt/first,/mnt/second ---------------------------------
Or in an array format:
----------------------------------path.data: ["/mnt/first", "/mnt/second"] -----------------------------

2，磁盘选择是shard级别，一旦shard分配，新数据就只会写到这个盘；如果有新的index，shard会分配到另外盘。
