This commit sets external nodes for integration tests to default to
using 512m of heap. This can be overridden using tests.heap.size (a
system property that we already use elesewhere for setting the size of
the heap for the test runner) or using tests.jvm.argline (this last one
takes precedence).
This commit sets the default min heap equal to the default max
heap. This is to align the default out-of-box settings with the heap
size bootstrap check.
Currently, when you set `include_in_all` on an object, it will propagate the
information to its sub mappers immediately. This is annoying because this is
done using a different mechanism than regular mapping updates.
This PR changes object fields to propagate the information at document parsing
time rather than when `include_an_all` is updated. While moving this cost to
document parsing time rather than mapping update time is probably a bad
trade-off, I am confident that this cost is very low and think this new way
makes things simpler.
This change converts AllocationDecider registration from push based on
ClusterModule to implementing with a new ClusterPlugin interface.
AllocationDecider instances are allowed to use only Settings and
ClusterSettings.
Previously this was possible, which was problematic when issuing a
request like `DELETE /-myindex`, which was interpretted as "delete
everything except for myindex".

Reindex intentionally tries to fail the search operation to make sure
that the exception flows back. The exception message changed so we
should catch the appropriate exception.
Most of the examples in the pipeline aggregation docs use a small
"sales" test data set and I converted all of the examples that use
it to `// CONSOLE`. There are still a bunch of snippets in the pipeline
aggregation docs that aren't `// CONSOLE` so they aren't tested. Most
of them are "this is the most basic form of this aggregation" so they
are more immune to errors and bit rot then the examples that I converted.
I'd like to do something with them as well but I'm not sure what.
Also, the moving average docs and serial diff docs didn't get a lot of
love from this pass because they don't use the test data set or follow
the same general layout.

Adds a class that records changes made to RoutingAllocation, so that at the end of the allocation round other values can be more easily derived based on these changes. Most notably, it:
- replaces the explicit boolean flag that is passed around everywhere to denote changes to the routing table. The boolean flag is automatically updated now when changes actually occur, preventing issues where it got out of sync with actual changes to the routing table.
- records actual changes made to RoutingNodes so that primary term and in-sync allocation ids, which are part of index metadata, can be efficiently updated just by looking at the shards that were actually changed.
Currently both `PUT` and `POST` can be used to create indices. This commit
removes support for `POST index_name` so that we can use it to index documents
with auto-generated ids once types are removed.

In addition to be an allocation decider, DiskThresholdDecider also
monitors the used disk in order to trigger a reroute when the thresholds
are crossed. This change splits out the settings for disk thresholds
into DiskThresholdSettings, and moves the monitoring to a new
DiskThresholdMonitor. DiskThresholdDecider is then in line with other
allocation deciders, needing only Settings and ClusterSettings for
construction, which will allow deguicing allocation deciders.
`LobObtainFailedException` should be reserved for on-disk locks that
Lucene attempts (like `write.lock`). This switches our in-memory
semaphore locks for shards to use a different exception. Additionally,
ShardLockObtainFailedException no longer subclasses IOException, since
no IO is being done is this case.
Resolves#19978
Currently plugins can not inspect or upgrade custom
meta data on startup. This commit allow plugins
to check and/or upgrade global custom meta data on startup.
Plugins can stop a node if any custom meta data is not supported.
This test was failing in the presence of transport clients. This turns
off transport clients while I fix the test so it doesn't fail for
everyone in the mean time.
The big change here is cleaning up the `TaskListResponse` so it doesn't
have a breaky `toString` implementation. That was causing the reindex
tests to break.
Also removed `NetworkModule#registerTaskStatus` which is part of the
Plugin API. Use `Plugin#getNamedWriteables` instead.
Primary shard allocation observes limits in forcing allocation
Previously, during primary shards allocation of shards
with prior allocation IDs, if all nodes returned a
NO decision for allocation (e.g. the settings blocked
allocation on that node), we would chose one of those
nodes and force the primary shard to be allocated to it.
However, this meant that primary shard allocation
would not adhere to the decision of the MaxRetryAllocationDecider,
which would lead to attempting to allocate a shard
which has failed N number of times already (presumably
due to some configuration issue).
This commit solves this issue by introducing the
notion of force allocating a primary shard to a node
and each decider implementation must implement whether
this is allowed or not. In the case of MaxRetryAllocationDecider,
it just forwards the request to canAllocate.
Closes#19446
In the example there was a alias removed and then a different alias created for the same index, but I think actually swapping a index by another one for the same alias would make more sense as an example here.
Parsing a search request is currently split up among a number of
classes, using multiple public static methods, which take multiple
regstries of elements that may appear in the search request like query
parsers and aggregations. This change begins consolidating all this code
by collapsing the registries normally used for parsing search requests
into a single SearchRequestParsers class. It is also made available to
plugin services to enable templating of search requests. Eventually all
of the actual parsing logic should move to the class, and the registries
should be hidden, but for now they are at least co-located to reduce the
number of objects that must be passed around.
