== Breaking changes in 2.2
|
|
|
|
This section discusses the changes that you need to be aware of when migrating
|
|
your application to Elasticsearch 2.2.
|
|
|
|

|
|
=== Scripting and security
|
|
|
|
The Java Security Manager is being used to lock down the privileges available
|
|
to the scripting languages and to restrict the classes they are allowed to
|
|
load to a predefined whitelist. These changes may cause scripts which worked
|
|
in earlier versions to fail. See <<modules-scripting-security>> for more
|
|
details.

|
|
=== Field stats API
|
|
|
|
The field stats' response format has been changed for number based and date
|
|
fields. The `min_value` and `max_value` elements now return values as number
|
|
and the new `min_value_as_string` and `max_value_as_string` return the values
|
|
as string.
|
|
|

|
|
=== Default logging using systemd
|
|
|
|
In previous versions of Elasticsearch using systemd, the default logging
|
|
configuration routed standard output to `/dev/null` and standard error to
|
|
the journal. However, there are often critical error messages at
|
|
startup that are logged to standard output rather than standard error
|
|
and these error messages would be lost to the ether. The default has
|
|
changed to now route standard output to the journal and standard error
|
|
to inherit this setting (these are the defaults for systemd). These
|
|
settings can be modified by editing the `elasticsearch.service` file.
|
|
|
|

|
|
=== Cloud AWS Plugin
|
|
|
|
Proxy settings have been deprecated and renamed:
|
|
|
|
* from `cloud.aws.proxy_host` to `cloud.aws.proxy.host`
|
|
* from `cloud.aws.ec2.proxy_host` to `cloud.aws.ec2.proxy.host`
|
|
* from `cloud.aws.s3.proxy_host` to `cloud.aws.s3.proxy.host`
|
|
* from `cloud.aws.proxy_port` to `cloud.aws.proxy.port`
|
|
* from `cloud.aws.ec2.proxy_port` to `cloud.aws.ec2.proxy.port`
|
|
* from `cloud.aws.s3.proxy_port` to `cloud.aws.s3.proxy.port`
|
|
|
|
If you are using proxy settings, update your settings as deprecated ones will
|
|
be removed in next major version.
|
|
|
|

|
|
=== Multicast plugin deprecated
|
|
|
|
The `discovery-multicast` plugin has been deprecated in 2.2.0 and has
|
|
been removed in 3.0.0.
