This commit is related to elastic/x-pack-elasticsearch#1896. Currently setup mode means that the
password must be set post 6.0 for using x-pack. This interferes with
upgrade tests as setting the password fails without a properly
upgraded security index.
This commit loosens two aspects of the security.
1. The old default password will be accept in setup mode (requests
from localhost).
2. All request types can be submitted in setup mode.

This is step 2 of elastic/x-pack-elasticsearch#1604
This change stores `model_memory_limit` as a string with `mb` unit.
I considered using the `toString` method of `ByteSizeValue` but it
can lead to accuracy loss. Adding the fixed `mb` unit maintains
the accuracy, while making clear what unit the value is in.

ML has two types of custom cluster state:
1. jobs
2. datafeeds
These need to be parsed from JSON in two situations:
1. Create/update of the job/datafeed
2. Restoring cluster state on startup
Previously we used exactly the same parser in both situations, but this
severely limits our ability to add new features. This is because the
parser was very strict. This was good when accepting create/update
requests from users, but when restoring cluster state from disk it meant
that we could not add new fields, as that would prevent reloading in
mixed version clusters.
This commit introduces a second parser that tolerates unknown fields for
each object that is stored in cluster state. Then we use this more
tolerant parser when parsing cluster state, but still use the strict
parser when parsing REST requests.

This is the x-pack side of https://github.com/elastic/elasticsearch/pull/24437
It changes two things, for the disable tests, it uses a valid endpoint instead
of a previously invalid endpoint that happened to return a 400 because the
endpoint was bad, regardless of if watcher was disabled.
The other change is to create the watches index by putting a watch using the
correct API, rather than manually creating the index. This is because
`RestHijackOperationAction` hijacks operations like this and stops accessing the
endpoint in a regular manner.

Currently, the autodetect process has an `ignoreDowntime`
parameter which, when set to true, results to time being
skipped over to the end of the bucket of the first data
point received. After that, skipping time requires closing
and opening the job. With regard to datafeeds, this does not
work well with real-time requests which use the advance-time
API in order to ensure results are created for data gaps.
This commit improves this functionality by making it more
flexible and less ambiguous.
- flush API now supports skip_time parameter which
sends a control message to the autodetect process
telling it to skip time to a given value
- the flush API now also returns the last_finalized_bucket_end
time which allows clients to resume data searches correctly
- the datafeed start API issues a skip_time request when the
given start time is after the resume point. It then resumes
the search from the last_finalized_bucket_end time.

Original commit: elastic/x-pack-elasticsearch@caa5fe8016
This fixes `testDeleteJobAfterMissingAliases` to not fail randomly.
The reason the test was failing is that at some point some aliases
are deleted and the cat-aliases API is called to verify they were
indeed deleted. This was checked by asserting an
index_not_found_exception was thrown by the cat-aliases request.
This was some times working as there were no other aliases. However,
that depends on whether other x-pack features had time to create their
infrastructure. For example, security creates an alias. When other
aliases had the time to be created, the cat-aliases request does not
fail and the test fails.
This commit simply changes the verification that the read/write
aliases were deleted by replacing the cat-aliases request with
two single get-alias requests.

that it is in setup mode. An elastic user in setup mode is only
authorized to execute a change password request.

The logic of resetting acknowledgements is only executed, if the watch

(which makes it always true), but create a condition in your action

then execute the condition), then after acking this action, it will
never get be unacked, because the watch wide condition is always met.

The .security index used several different types to differentiate the
documents added to the index (users, reserved-users, roles, etc). Since
types are deprecated in 6.x, this commit changes the .security index
access layer to only use a single type and have all documents in the
index be of that single type. To differentiate documents that may have
the same id (e.g. the same user name and role name), the appropriate
type of the document is prepended to the id. For example, a user named
"jdoe" will now have the document id "user-jdoe".
This commit also ensures that any native realm security index operations
that lead to auto creation of the security index first go through the process
of creating the internal security index (.security-v6) and creating the alias
.security to point to the internal index.
Lastly, anytime the security index is accessed without having been
upgraded, an exception is thrown notifying the user to use the
upgrade API to upgrade the security index.

there does not need to be complicated logic between the two. Note that
the old settings remain the only way to set the ssl passphrases for the

created in memory by users, so they are already as "secure" as having a
loaded ES keystore. Also note that in the long term future (6.x

themselves should be moved into the ES keystore, so there will be no

If multiple job deletion requests were sent in quick succession, there was a
race condition that meant they could both get through the check to enforce
one active deletion request at a time. Then, if the job was immediately
recreated after the first deletion request returned, the second, still running,
deletion request could interfere with it and delete the aliases that the put
job request created.
This problem can be avoided by using the "ask forgiveness, not permission"
idiom when checking if the job is already being deleted at the beginning of
each deletion request.
Additionally, now even force delete requests will wait for a certain amount
of time for a prior delete request to complete. This is to avoid the same
race conditions. However, force delete requests will eventually start an
(unsafe) parallel delete to provide a get-out in case a delete request
completely dies.

Prior to this change, if the persistent tasks framework noticed that a
job was running on a node that was isolated but has rejoined the cluster
then it would close that job. This was not ideal, because then the job
would persist state from the autodetect process that was isolated. This
commit changes the behaviour to kill the autodetect process associated
with such a job, so that it does not interfere with the autodetect process
that is running on the node where the persistent tasks framework thinks it
should be running.
In order to achieve this a change has also been made to the behaviour of
force-close. Previously this would result in the autodetect process being
gracefully shut down asynchronously to the force-close request. However,
the mechanism by which this happened was the same as the mechanism for
cancelling tasks that end up running on more than one node due to nodes
becoming isolated from the cluster. Therefore, force-close now also kills
the autodetect process rather than gracefully stopping it. The documentation
has been changed to reflect this. It should not be a problem as force-close
is supposed to be a last resort for when normal close fails.

In the case where a field is a text multi-field, it has
no doc values and it is not in source. Thus, the datafeed
will not be able to extract it.

In 5.4.x, the datafeed attempts to get all fields from
doc_values by default. It has a `_source` parameter which
when enabled changes the strategy to instead try to get
all fields from the source.
This has been the most common issue users have been
reporting as it means the datafeed will fail to fetch
any text fields by default.
This change uses the field capabilities API in order
to automatically detect whether a field is aggregatable.
It then extracts such fields from doc_values while the
rest are taken from source. The change also adds
validation to the start datafeed action so that if
fields are missing mappings or the time field is not
aggregatable we respond with an appropriate error.

This is mainly a commit to reduce noise in test logfiles when going
through them. When watcher shuts down and another node takes over, it
might try to start watcher again and tries to load triggered watches.

does not exist.

number of replicas.
This feature was not exposed in our documentation at all.
