there are 7 elasticsearch instance , node 4 and node6 are coordination node . I send rest http request to node 4 and node6 (data=false & master = false ), but i found the io-read in node1 heavily higher than other nodes , nearly 300 M/s and other nodes nearly 0 . The request searches a 60 indices combined alias indices(daily managed indices ) ,the primary and the replicated shard located balance in different node . Why?
