Hi all.
I'm reposting an earlier thread of mine with a more appropriate subject in
hopes that someone might have an idea on this one. 
Each node in my cluster has its configuration set via elasticsearch.yml
only. I do not apply any index level settings, however the nodes in the
cluster are overwriting my config settings with the defaults. I have been
unable to figure out why this is happening, and was hoping someone else
might.
My elasticsearch.yml file defines these settings:
index:
codec:
bloom:
load: false
merge:
policy:
max_merge_at_once: 4
max_merge_at_once_explicit: 4
max_merged_segment: 1gb
segments_per_tier: 4
type: tiered
scheduler:
max_thread_count: 1
type: concurrent
number_of_replicas: 0
number_of_shards: 1
refresh_interval: 5s
From the head plugin, I can see these settings are in effect:
- settings: {
- index: {
- codec: {
- bloom: {
- load: false
}
}
- number_of_replicas: 1
- number_of_shards: 6
- translog: {
- flush_threshold_size: 1GB
}
- search: {
- slowlog: {
- threshold: {
- fetch: {
- warn: 2s
- info: 1s
}
- index: {
- warn: 10s
- info: 5s
}
- query: {
- warn: 10s
- info: 5s
}
}
}
}
- refresh_interval: 60s
- merge: {
- scheduler: {
- type: concurrent
- max_thread_count: 1
}
- policy: {
- type: tiered
- max_merged_segment: 1gb
- max_merge_at_once_explicit: 4
- max_merge_at_once: 4
- segments_per_tier: 4
}
}
}
- bootstrap: {
- mlockall: true
}
-
But each node outputs this on new index creation:
[2015-01-13 02:12:52,062][INFO ][index.merge.policy ]
[elasticsearch-test] [test-20150113][1] updating [segments_per_tier] from

This is happening both on two clusters for me. My "regular" ES cluster of
3 nodes, and my dedicated Marvel cluster of 1 node. So strange.

I am really stumped on why this is happening!
Thanks so much for your time.
