=== Settings changes
|
|
|
|
==== Remove support for elasticsearch.json and elasticsearch.yaml configuration file
|
|
|
|
The configuration file found in the Elasticsearch config directory could previously have
|
|
a `.yml`, `.yaml` or `.json` extension. Only `elasticsearch.yml` is now supported.
|
|
|
|
==== Duplicate keys in configuration file
|
|
|
|
In previous versions of Elasticsearch, the configuration file was allowed to
|
|
contain duplicate keys. For example:
|
|
|
|
[source,yaml]
|
|
--------------------------------------------------
|
|
node:
|
|
name: my-node
|
|
|
|
node
|
|
attr:
|
|
rack: my-rack
|
|
--------------------------------------------------
|
|
|
|
In Elasticsearch 6.0.0, this is no longer permitted. Instead, this must be
|
|
specified in a single key as:
|
|
|
|
[source,yaml]
|
|
--------------------------------------------------
|
|
node:
|
|
name: my-node
|
|
attr:
|
|
rack: my-rack
|
|
--------------------------------------------------
|
|
|
|
==== Coercion of boolean settings
|
|
|
|
Previously, Elasticsearch recognized the strings `true`, `false`, `on`, `off`, `yes`, `no`, `0`, `1` as booleans. Elasticsearch 6.0
|
|
recognizes only `true` and `false` as boolean and will throw an error otherwise. For backwards compatibility purposes, during the 6.x series
|
|
index settings on pre-6.0 indices will continue to work. Note that this does not apply to node-level settings that are stored
|
|
in `elasticsearch.yml`.
|
|
|
|
==== Snapshot settings
|
|
|
|
The internal setting `cluster.routing.allocation.snapshot.relocation_enabled` that allowed shards with running snapshots to be reallocated to
|
|
different nodes has been removed. Enabling this setting could cause allocation issues if a shard got allocated off a node and then
|
|
reallocated back to this node while a snapshot was running.
|
|
|
|
==== Store throttling settings
|
|
|
|
Store throttling has been removed. As a consequence, the
|
|
`indices.store.throttle.type` and `indices.store.throttle.max_bytes_per_sec`
|
|
cluster settings and the `index.store.throttle.type` and
|
|
`index.store.throttle.max_bytes_per_sec` index settings are not
|
|
recognized anymore.
|
|
|
|
==== Store settings
|
|
|
|
The `default` `index.store.type` has been removed. If you were using it, we
|
|
advise that you simply remove it from your index settings and Elasticsearch
|
|
will use the best `store` implementation for your operating system.
|
|
|
|
==== Network settings
|
|
|
|
The blocking TCP client, blocking TCP server, and blocking HTTP server have been removed.
|
|
As a consequence, the `network.tcp.blocking_server`, `network.tcp.blocking_client`,
|
|
`network.tcp.blocking`,`transport.tcp.blocking_client`, `transport.tcp.blocking_server`,
|
|
and `http.tcp.blocking_server` settings are not recognized anymore.
|
|
|
|
==== Similarity settings
|
|
|
|
The `base` similarity is now ignored as coords and query normalization have
|
|
been removed. If provided, this setting will be ignored and issue a
|
|
deprecation warning.
|
|
|
|
==== Script Settings
|
|
|
|
All of the existing scripting security settings have been deprecated. Instead
|
|
they are replaced with `script.allowed_types` and `script.allowed_contexts`. |
