Elasticsearch 6.

Is there a nice way to get a list of indices shards of which are on a given node? The only way I can find is to call `_cat/shards` and grep the output for the node name. Node information in Kibana Monitoring shows which indices are on that node but I don't know how it gets that list.

Since making the previous post I've realised that what I actually want is a way to set settings for all indices with shards on a node and only those indices. But I can't see a way to do that, other than to get a list of what's on a given node and then parse that. And making use of such a list could be quite tediously slow and/or fiddly even when automated because I'm working with nodes that have shards from ~500 indices on and putting the names of all those in to a single curl command like `index1,index2,index3` doesn't work because the list is too long so it would have to be done in chunks.

What I'd like to do is set `index.unassigned.node_left.delayed_timeout` as described at [https://www.elastic.co/guide/en/elasticsearch/reference/6.8/delayed-allocation.html](https://www.elastic.co/guide/en/elasticsearch/reference/6.8/delayed-allocation.html) on all the indices shards of which are on a node just before it's temporarily taken out of the cluster for maintenance. I could just set it on all indices, but I'd prefer to set it only on indices which are actually affected by the node going away.
