Breaking changes in 7.2
editBreaking changes in 7.2
editThis section discusses the changes that you need to be aware of when migrating your application to Elasticsearch 7.2.
See also What’s new in 7.16 and Release notes.
Discovery changes
editOnly a single port may be given for each seed host.
editIn earlier versions you could include a range of ports in entries in the
discovery.seed_hosts
list, but Elasticsearch used only the first port in the range and
unexpectedly ignored the rest. For instance if you set discovery.seed_hosts:
"10.11.12.13:9300-9310"
then Elasticsearch would only use 10.11.12.13:9300
for
discovery. Seed host addresses containing port ranges are now rejected.
Index lifecycle management (ILM) deprecations
editAn ILM poll interval of less than one second is deprecated.
editSetting indices.lifecycle.poll_interval
to less than one second (1s
) is now
deprecated. If the indices.lifecycle.poll_interval
cluster setting is too low,
it can cause excessive load on a cluster.
To avoid deprecation warnings, use a setting value of 1s
or greater.
Ingest pipeline changes
editThe user_agent
ingest processor’s ecs
parameter is deprecated.
editThe ecs
parameter for the user_agent
ingest processor is deprecated and will
be removed in 8.0. In 8.x, the user_agent
ingest processor will only return
Elastic Common Schema (ECS) fields.
To avoid deprecation warnings, remove the parameter from your ingest pipelines.
