An infrastructure that allows to simulate different network topologies failures, including 2 basic ones in failure to send requests, and unresponsive nodes
closes#5631
Today the clusterstate is not asssociated with the cluster_name which is odd
since it's pretty much it's only valid identifier. Any node can send a cluster
state to another node today even if it's not the same cluster. These situations
can happen rarely during tests or even in the wild by accident.
- removed an abstraction layer that handles the values source (consolidated values source with field data source)
- better handling of value parser/formatter in range & histogram aggs
- the buckets key will now be shown by default in range agg
simplify rest response class hierarchy, by using BytesReference for content, and handling JSONP internally in the respective channel that sends the response.
Also, handle the future case where bytes might be releasable, when we start to potentially recycle bytes output stream.
A bunch of minor fixes have been included here, especially due
to wrongly parsed mappings. Also using assertions resulted in an
NPE because they were disabled in the distribution.
Closes#5525
The new base class contains all the immutable methods for a cluster, which will be extended by the future ExternalCluster impl that relies on an external cluster and won't be adding nodes etc. but only sending requests to an existing cluster whose layout never changes
Closes#5620
Before a bulk request is executed, missing indices are being created by default.
If this fails, the whole request is failed.
This patch changes the behaviour to not fail the whole request, but rather all
requests using the index where the creation has failed.
Closes#4987
If a node fails to forward a master node operation to the current master, it will schedule a retry using a listener for cluster state changes. Once the listener is in place (and future changes are guaranteed to be observed) it will double check nothing has change during the addition of the listener. This check has previously been change to use cluster state versions (see: #5499). This is however not reliable solution as master elections (which change the master) do not increment the cluster state version and thus could be missed. This commit changes the check to use reference equality making it stricter.
Closes#5548
Although high-severity bugs were mostly static variables that were not final,
it also found potential NPEs and bugs like `x ^= x;` or equality checks on
objects that don't share a common interface.
Close#5571
For around 10% of the calls that support the GET method, the request body gets now sent as `source` parameter with GET method (no randomized method in this case).
This way we can find bugs like #5556 (missing support for source param).
Some tests disable refresh and verify that documents cannot be found without an explicit refresh. With at least one replica and waiting for yellow though, it can happen that we start indexing docs when the replicas are not ready yet, and as soon as they become ready they get refreshed, causing the newly added docs to be unexpectedly found. Solution is to disable replicas for these specific tests.
The `field_value_factor` function uses the value of a field in the
document to influence the score.
A query that looks like:
{
"query": {
"function_score": {
"query": {"match": { "body": "foo" }},
"functions": [
{
"field_value_factor": {
"field": "popularity",
"factor": 1.1,
"modifier": "square"
}
}
],
"score_mode": "max",
"boost_mode": "sum"
}
}
}
Would have the score modified by:
square(1.1 * doc['popularity'].value)
Closes#5519
allow to configure on the index level which blocks can optionally be applied using tribe.blocks.indices prefix settings.
allow to control what will be done when a conflict is detected on index names coming from several clusters using the tribe.on_conflict setting. Defaults remains "any", but now support also "drop" and "prefer_[tribeName]".
