Elasticsearch breaking changes
editElasticsearch breaking changes
editThis list summarizes the most important breaking changes in Elasticsearch 7.8.1. For the complete list, go to Elasticsearch breaking changes.
License Information changes
editAs of the 7.8.1
release
Displays Enterprise license as Platinum in /_xpack
Details
The GET /_license
endpoint displays Enterprise licenses as
Platinum by default so that old clients (including Beats, Kibana and
Logstash) know to interpret this new license type as if it were a
Platinum license.
This compatibility layer was not applied to the GET /_xpack/
endpoint, which also displays a license type and mode. #58217
Aggregation changes
editPrivilege indices:admin/create
will no longer allow the auto creation of indices
Details
The privilege named indices:admin/create
will no longer allow the auto
creation of indices. Use create_index
instead. #55858
value_count
aggregation optimization
Details
Scripts used in value_count
will now receive a number if they are
counting a numeric field and a GeoPoint
if they are counting a
geo_point
fields. They used to always receive the String
representation of those values. #54854
Mappings changes
editThe enabled
mapping parameter cannot be changed for a root mapping.
Details
Mapping requests that attempt to change the enabled
mapping parameter for a root mapping will fail and return an error.
Previously, Elasticsearch accepted mapping requests that attempted to change the
enabled
parameter of the root mapping. Theses changes were not applied, but
such requests didn’t return an error.
Impact
To avoid errors, do not submit mapping requests that change the
enabled
mapping parameter.
The include_in_parent
and include_in_root
mapping parameters cannot be changed for nested
fields.
Details
Mapping requests that attempt to change the
include_in_parent
or
include_in_root
mapping
parameter for a nested
field will fail and return an error.
Previously, Elasticsearch accepted mapping requests that attempted to change the
include_in_parent
or include_in_root
parameter. Theses changes were not
applied, but such requests didn’t return an error.
Impact
To avoid errors, do not submit mapping requests that change the
include_in_parent
or
include_in_root
mapping
parameter.
The get field mapping API’s local
query parameter is deprecated.
Details
The get field mapping API's local
query
parameter is deprecated and will be removed in Elasticsearch 8.0.0.
The local
parameter is a no-op. The API always retrieves field mappings
locally.
Impact
To avoid deprecation warnings, discontinue use of the local
parameter.
Security changes
editThe xpack.security.transport.ssl.enabled
setting will be required to configure xpack.security.transport.ssl
settings.
Details
Configuring any SSL settings for
xpack.security.transport.ssl
without also configuring
xpack.security.transport.ssl.enabled
generates warnings in the deprecation
log. In 8.0, this configuration will result in errors.
Impact
To avoid deprecation warnings, either:
-
Explicitly set
xpack.security.transport.ssl.enabled
asfalse
-
Discontinue use of other
xpack.security.transport.ssl
settings
If you want to enable SSL, follow the instructions to
encrypt communications between nodes. As part of this configuration, explicitly set
xpack.security.transport.ssl.enabled
as true
.
For example:
The xpack.security.http.ssl.enabled
setting will be required to configure xpack.security.http.ssl
settings.
Details
Configuring any SSL settings for xpack.security.http.ssl
without also
configuring xpack.security.http.ssl.enabled
generates warnings in the
deprecation log. In 8.0, this configuration will result in errors.
Impact
To avoid deprecation warnings, either:
-
Explicitly set
xpack.security.http.ssl.enabled
asfalse
-
Discontinue use of other
xpack.security.http.ssl
settings
If you want to enable SSL, follow the instructions to
encrypt HTTP client communications for Elasticsearch. As part
of this configuration, explicitly set xpack.security.http.ssl.enabled
as true
.
For example:
A xpack.security.transport.ssl
certificate and key will be required to enable SSL for the transport interface.
Details
Enabling SSL for the transport interface without also configuring a certificate
and key through use of the xpack.security.transport.ssl.keystore.path
setting or the xpack.security.transport.ssl.certificate
and
xpack.security.transport.ssl.key
settings generates warnings in the
deprecation log. In 8.0, this configuration will result in errors.
Impact
If xpack.security.transport.ssl.enabled
is set to true
, provide a
certificate and key using the xpack.security.transport.ssl.keystore.path
setting or the xpack.security.transport.ssl.certificate
and
xpack.security.transport.ssl.key
settings. If a certificate and key is not
provided, Elasticsearch will generate warnings in the deprecation log.
A xpack.security.http.ssl
certificate and key will be required to enable SSL for the HTTP layer.
Details
Enabling SSL for the HTTP layer without also configuring a certificate and key
through use of the xpack.security.http.ssl.keystore.path
setting or
the xpack.security.http.ssl.certificate
and xpack.security.http.ssl.key
settings generates warnings in the deprecation log. In 8.0, this configuration
will result in errors.
Impact
If xpack.security.http.ssl.enabled
is set to true
, provide a
certificate and key using the xpack.security.http.ssl.keystore.path
setting or the xpack.security.http.ssl.certificate
and
xpack.security.http.ssl.key
settings. If a certificate and key is not
provided, Elasticsearch will generate warnings in the deprecation log.
Settings changes
editThe node.local_storage
setting is deprecated.
Details
The node.local_storage
setting is deprecated. In Elasticsearch 8.0.0, all nodes require
local storage.
Impact
To avoid deprecation warnings, discontinue use of the node.local_storage
setting.
Several X-Pack settings no longer have any effect and are deprecated.
Details
Basic X-Pack license features are always enabled for the default distribution
and the following settings no longer have any effect:
-
xpack.enrich.enabled
-
xpack.flattened.enabled
-
xpack.ilm.enabled
-
xpack.monitoring.enabled
-
xpack.rollup.enabled
-
xpack.slm.enabled
-
xpack.sql.enabled
-
xpack.transform.enabled
-
xpack.vectors.enabled
Previously, they could be set to false
to disable the feature’s APIs in a cluster.
Impact
To avoid deprecation warnings, discontinue use of these settings.
If you have disabled ILM so that you can use another tool to manage Watcher
indices, the newly introduced xpack.watcher.use_ilm_index_management
setting
may be set to false.
Changes to built-in users
editThe kibana
user has been deprecated in favor of the kibana_system
user.
Details
The kibana
user was historically used to authenticate Kibana to Elasticsearch.
The name of this user was confusing, and was often mistakenly used to login to Kibana.
We’ve replaced the kibana
user with the kibana_system
user to reduce
confusion and to better align with other built-in system accounts.
Impact
If your kibana.yml
used to contain:
elasticsearch.username: kibana
then you should update to use the new kibana_system
user instead:
elasticsearch.username: kibana_system
The new kibana_system
user does not preserve the previous kibana
user password. You must explicitly set a password for the kibana_system
user.
Changes to built-in roles
editThe kibana_user
role has been deprecated in favor of the kibana_admin
role.
Details
Users who were previously assigned the kibana_user
role should instead be assigned
the kibana_admin
role. This role grants the same set of privileges as kibana_user
, but has been
renamed to better reflect its intended use.
Impact
Assign users with the kibana_user
role to the kibana_admin
role.
Discontinue use of the kibana_user
role.
Cluster coordination changes
editThe voting configuration exclusions API’s POST _cluster/voting_config_exclusions/<node_name>
request path is deprecated.
Details
The voting configuration exclusions API’s
POST _cluster/voting_config_exclusions/<node_name>
request path is now
deprecated. To add a voting configuration exclusion, specify node names or node
IDs using a query parameter instead:
-
POST _cluster/voting_config_exclusions?node_names=<node_names>
-
POST _cluster/voting_config_exclusions?node_ids=<node_ids>
Impact
To avoid deprecation warnings, discontinue use of the
POST _cluster/voting_config_exclusions/<node_name>
request path.
Transforms changes
editThe max_page_search_size
property is deprecated in the pivot
transform configuration object
Details
The max_page_search_size
property within pivot
is deprecated in the
create transform and
preview transform APIs.
Impact
Use the max_page_search_size
property within settings
instead.
