*Details* +

The following settings have been deprecated in 7.x and removed in 8.0. Each setting has a replacement
|

|
|
|
- `transport.tcp.port` replaced by `transport.port`
|
|
- `transport.tcp.compress` replaced by `transport.compress`
|
|
- `transport.tcp.connect_timeout` replaced by `transport.connect_timeout`
|
|
- `transport.tcp_no_delay` replaced by `transport.tcp.no_delay`
|
|
- `transport.profiles.profile_name.tcp_no_delay` replaced by `transport.profiles.profile_name.tcp.no_delay`
|
|
- `transport.profiles.profile_name.tcp_keep_alive` replaced by `transport.profiles.profile_name.tcp.keep_alive`
|
|
- `transport.profiles.profile_name.reuse_address` replaced by `transport.profiles.profile_name.tcp.reuse_address`

*Impact* +
|
|
Use the replacement settings. Discontinue use of the removed settings.
|
|
Specifying the removed settings in `elasticsearch.yml` will result in an error
|
|
on startup.

====
|
|
|
|
.The `es.unsafely_permit_handshake_from_incompatible_builds` system property has been removed.
|
|
[%collapsible]
|
|
====
|
|
*Details* +
|
|
{es} has a check that verifies that communicating pairs of nodes of the same
|
|
version are running exactly the same build and therefore using the same wire
|
|
format as each other. In previous versions this check can be bypassed by
|
|
setting the system property
|
|
`es.unsafely_permit_handshake_from_incompatible_builds` to `true`. The use of
|
|
this system property is now forbidden.
|
|
|
|
*Impact* +
|
|
Discontinue use of the `es.unsafely_permit_handshake_from_incompatible_builds`
|
|
system property, and ensure that all nodes of the same version are running
|
|
exactly the same build. Setting this system property will result in an error
|
|
on startup.
