This change adds a grok_pattern field to the GET categories API
output in ML. It's calculated using the regex and examples in the
categorization result, and applying a list of candidate Grok
patterns to the bits in between the tokens that are considered to
define the category.
This can currently be considered a prototype, as the Grok patterns
it produces are not optimal. However, enough people have said it
would be useful for it to be worthwhile exposing it as experimental
functionality for interested parties to try out.
This commit removes the unnecessary transport_client cluster permission
from the role that is used as an example in our documentation. This
permission is not needed to use cross cluster search.
This commit removes the http.enabled setting. While all real nodes (started with bin/elasticsearch) will always have an http binding, there are many tests that rely on the quickness of not actually needing to bind to 2 ports. For this case, the MockHttpTransport.TestPlugin provides a dummy http transport implementation which is used by default in ESIntegTestCase.
closes#12792
This is related to #30134. It modifies the start_trial action to require
an acknowledgement parameter in the rest request to actually start the
trial license. There are backwards compatibility issues as prior ES
versions did not support this parameter. To handle this, it is assumed
that a request coming from a node prior to 6.3 is acknowledged. And
attempts to write a non-acknowledged request to a prior to 6.3 node will
throw an exception.
Additionally this PR adds messages about the trial license the user is
generating.
