With #12921 we refactored IndicesModule but we forgot to make sure we create IndicesQueriesRegistry once. IndicesQueriesModule used to do `bind(IndicesQueriesRegistry.class).asEagerSingleton();` otherwise we get multiple instances of the registry. This needs to be ported do the IndicesModule.
It was already disabled, but during tests the test framework enabled the query cache by setting the static default query cache. The caching behaviour should be the same in production and in tests.
This move the `murmur3` field to the `mapper-murmur3` plugin and fixes its
defaults so that values will not be indexed by default, as the only purpose
of this field is to speed up `cardinality` aggregations on high-cardinality
string fields, which only requires doc values.
I also removed the `rehash` option from the `cardinality` aggregation as it
doesn't bring much value (rehashing is cheap) and allowed to remove the
coupling between the `cardinality` aggregation and the `murmur3` field.
Close#12874
The Plugin interface currently contains 6 different methods for
adding modules. Elasticsearch has 3 different levels of injectors,
and for each of those, there are two methods. The first takes no
arguments and returns a collection of class objects to construct. The
second takes a Settings object and returns a collection of module
objects already constructed. The settings argument is unecessary because
the plugin can already get the settings from its constructor. Removing
that, the only difference between the two versions is returning an
already constructed Module, or a module Class, and there is no reason
the plugin can't construct all their modules themselves.
This change reduces the plugin api down to just 3 methods for adding
modules. Each returns a Collection<Module>. It also removes the
processModule method, which was unnecessary since onModule
implementations fullfill the same requirement. And finally, it renames
the modules() method to nodeModules() so it is clear these are created
once for each node.
java.net.preferIPv6Addresses is a better choice. preferIPv4Stack is a nuclear option
and you just won't even bind to any IPv6 addresses. This reduces confusion.
The restore portion of some snapshot/restore test is failing randomly due to #9421. This change suspends rebalance during snapshot/restore operations until #9421 is fixed.
Closes#12855
Plugins can preovide additional settings to be added to the settings
provided in elasticsearch.yml. However, if two different plugins supply
the same setting key, the last one to be loaded wins, which is
indeterminate. This change enforces plugins cannot have conflicting
settings, at startup time. As a followup, we should do this when
installing plugins as well, to give earlier errors when two plugins
collide.
Custom repository types are registered through the RepositoriesModule.
Later, when a specific repository type is used, the RespositoryModule
is installed, which in turn would spawn the module that was
registered for that repository type. However, a module is not needed
here. Each repository type has two associated classes, a Repository and
an IndexShardRepository.
This change makes the registration method for custom repository
types take both of these classes, instead of a module.
See #12783.
When elasticsearch is configured by interface (or default: loopback interfaces),
bind to all addresses on the interface rather than an arbitrary one.
If the publish address is not specified, default it from the bound addresses
based on the following sort ordering:
* ipv4/ipv6 (java.net.preferIPv4Stack, defaults to true)
* ordinary addresses
* site-local addresses
* link local addresses
* loopback addresses
One one address is published, and multicast is still always over ipv4: these
need to be future improvements.

EsExecutorsTests had a test that was failing spuriously due to threadpools
being threadpools. This weakens the assertions that the test makes to what
should always be true.
It might turn out to be useful to have the actual commit hash of the version we are
looking for if our download manager can just redirect to the right staging repository.
This is purely for maintainance reasons since it easier to see if we can drop
certain stageing urls if we have the version next to the hash.
I also removed the gpg passphrase from the example URL since it's better to get prompted?
This is caused by sending the same file to the chunk handler with offset
`0` which in-turn opens a new outputstream and waits for bytes. But the next round
will send 0 bytes again with offset 0. This commit adds some checks / validators that those
settings are positive byte values and fixes the RecoveryStatus to throw an IAE if the same file
is opened twice.
What is the problem we are trying to solve ?
===========================================
When we are doing aggregations against a field name as shown in
https://github.com/HarishAtGitHub/elasticsearch-tester/blob/master/12135.py#L37-L46
search = {
"aggs": {
"NAME": {
"terms": {
"field": "ip_str",
"size": 10
}
}
}
}
and when the field "ip_str" has values of different types in different indices
. say one is of type StringTerms type and other is of IP(LongTerms type) then
the aggregation fails as the types do not match(incompatible).
The failure throws a class cast exception as follows:
{
"error": {
"root_cause": [],
"type": "reduce_search_phase_exception",
"reason": "[reduce] ",
"phase": "query",
"grouped": true,
"failed_shards": [],
"caused_by": {
"type": "class_cast_exception",
"reason": "org.elasticsearch.search.aggregations.bucket.terms.LongTerms$Bucket cannot be cast to org.elasticsearch.search.aggregations.bucket.terms.StringTerms$Bucket"
}
},
"status": 503
}
which is hard to understand . User cannot infer anything about the cause of the problem and what he should do from seeing the
class cast exception.
What can be the possible solution ?
===================================
Make the exception more readable by showing him the root cause of the problem so that he can
understand which area actually caused the problem, so that he can take necessary steps further.
Code Analysis
=============
Debugging code shows that:
the query /{indices}/_search?search_type=count involves two phases
1) search phase
***************
searchService.sendExecuteQuery(...) [Ref: TransportSearchCountAction]
what happens here ?
the phase 1, which is the search phase goes without error.
In this phase the shards for the given indexes are collected and the search is done on all asynchronously
and finally collected in the variable "firstResults" and given to meger phase.
[Flow: .... -> TransportSearchTypeAction -> method performFirstPhase]
2) merge phase
**************
searchPhaseController.merge(...firstResults...) [Ref: TransportSearchCountAction]
what happens here ?
the "firstresults" QuerySearchResults are now to be aggregated and combined.
[Flow: SearchPhaseController.merge(...) -> ..... -> InternalTerms.doReduce(...)]
the phase 1, which is the search phase goes without error.
The problem comes in phase 2, which is merge phase.
Now the individual term buckets are available.
As per the test case , there are two indices cast and cast2, so by default 10 shards.
cast has ip_str of type StringTerms
cast2 has ip_str of type ip which is actually LongTerms
so here two types of Buckets exist. StringTerms_Bucket and LongTerms_Bucket.
Now the aggregation is to be put inside the BucketPriorityQueue(size 2: as out of 10, 2 has hits) finally.
(docs of PriorityQueue: https://lucene.apache.org/core/4_4_0/core/org/apache/lucene/util/PriorityQueue.html#insertWithOverflow(T))
Now first the LongTerms$Bucket is put inside.
then the StringTerms$Bucket is to be put in.
This is the area where exception is thrown. What happens is when adding the StringTerms$Bucket now it has to
goes through the code "lessThan(element, heap[1])"
which finally calls
---------------------------------------------------------------------------------------------
| StringTerms$Bucket.compareTerms(other) <---------------- Area of exception |
| |
--------------------------------------------------------------------------------------------
where when comparing one to other a type cast is done and it fails as StringTerms$Bucket and LongTerms$Bucket are
incompatible.
Approach to solve:
==================
The best way is to make user understand that the problem is when reducing/merging/aggregating the buckets which came as a result of
querying different shards, so that this will make them infer that the problem is because the values of the fields are of different types.
The message is also user friendly and much better than the indecipherable classcastexception.
The only place to infer correctly that the aggregation has failed is in the place where aggregations take place.
so
at InternalTerms.java -> (BucketPriorityQueue)ordered.insertWithOverflow(b);
so here I can throw AggregationExecutionException saying it is because the buckets are of different
types.
But when can I infer at this point that the failure is due to mismatch of types of buckets ???
it can be possible only if at this point it is informed that the problem which occurred deep inside
is due to buckets that were incomparable.
so from just a classCastException we cannot make such a pointed exact inference, because
as class cast exception can be due to a number of scenarios and at a number of places.
so unless we inform the exact problem to InternalTerms it will not be able to infer properly.
so infer the classCastException at the compareTerms function itself that it is a IncomparableTermBucktesTypeException.
This is the best place to infer classCastException as this the place which generated the exception.
Best inference of exceptions can be done only at the source/origin of the exception.
so IncomparableTermBucktesTypeException to InternalTerms-> will make it infer and conclude on why
aggregation failed and give best information to user.
Close#12821
The IndicesModule was made up of two submodules, one which
handled registering queries, and the other for registering
hunspell dictionaries. This change moves those into
IndicesModule. It also adds a new extension point type,
InstanceMap. This is simply a Map<K,V>, where K and V are
actual objects, not classes like most other extension points.
I also added a test method to help testing instance map extensions.
This was particularly painful because of how guice binds the key
and value as separate bindings, and then reconstitutes them
into a Map at injection time. In order to gain access to the
object which links the key and value, I had to tweak our
guice copy to not use an anonymous inner class for the Provider.
Note that I also renamed the existing extension point types, since
they were very redundant. For example, ExtensionPoint.MapExtensionPoint
is now ExtensionPoint.ClassMap.
See #12783.
shard variable dependency from processFirstPhaseResults as shard is no more
needed here . it only deals with the results obtained from the synchronous search on each shard.
The ClusterModule contained a couple submodules. This moves the
functionality from those modules into ClusterModule. Two of those
had to do with DynamicSettings. This change also cleans up
how DynamicSettings are built, and enforces they are added, with
validators, in ClusterModule.
See #12783.
Previously settings specified in index templates were not validated upon
template creation. Creating an index from an index template with invalid
settings could lead to cluster stability issues because creation of such
indexes would bypass index settings validation.
This commit adds validation of settings specified in index templates at
template creation time. This works by routing the index template
settings through the index settings validation mechanism.
Closes#12865
Users with IPv6 preferred over IPv4 may have `localhost` resolve to
`::1` instead of `127.0.0.1`, so we should be explicit so they don't run
into issues.
Today on a failure the reproduce line printed out by the test framework
will build all projects and might fail if the test class is not present.
This commit adds a reactor filter to the reproduction line to ensure
unrelated projects are skipped.
Closes#12838
In order to match the paths of official plugins, we need to fix
the broken test by removing the elasticsearch prefix from the official
plugin names before testing.
This PR adds a timezone field to ValueParser.DateMath that is
set to UTC by default but can be set using the existing constructors.
This makes it possible for extended bounds setting in DateHistogram
to also use date math expressions that e.g. round by day and apply
this rounding in the time zone specified in the date histogram
aggregation request.
Closes#12278
In order to create releases without actually changing the version
as part of a commit, we also need to reflect the path of the potentially
changing S3 repo.
This method has multiple modes of resolving config files by
first looking in the config directory, then on the classpath,
and finally by prefixing with "config/" on the classpath.
Most of the places taking advantage of this were tests, so they
did not have to setup a real home dir with config. The only place
that was really relying on it was the code which loads names.txt
to randomly choose a node name.
This change fixes test to setup fake home dirs with their config
files. It also makes the logic for finding names.txt explicit:
look in config dir, and if it doesn't exist, load /config/names.txt
from the classpath.
TermsQueryParser still parses those values although deprecated. These need to be present in the java api as well to get ready for the query refactoring, where the builders are the intermediate query format that we parse our json queries into. Whatever the parser supports need to be supported by the builder as well.
Closes#12870
TermsQueryParser doesn't support the cache field anymore, so if it gets set through java api, the subsequent parsing of that query will throw error
Relates to #12870
Refactored a part out of the release script, so the user can
change the version locally as well as move the documentation
and change the Version.java
The background of this change is to have a very simple release
process that puts stuff into a staging environment, so the beta
release can be tested, before it is officially released.
This means the build_release script can be removed soon.
Settings currently has a classloader member, which any user (plugin
or core ES code) can access to load classes/resources. This is extremely
error prone as setting the classloder on the Settings instance is a
public method. Furthermore, it is not really necessary. Classes that
need resources should load resources using normal means
(getClass().getResourceAsStream). Those that need classes
should use Class.forName, which will load the class with the
same classloader as the calling class. This means, in the few
places where classes are loaded by string name, they will use
the appropriate loader: either the default classloader which loads
core ES code, or a child classloader for each plugin.
This change removes the classloader member from Settings, as
well as other classloader related uses (except for a handful
of cases which must use a classloader, at least for now).
We previous used something like Class.forName to load mock classes,
where tests would set a setting that was *supposed* to only be used by
tests. This change make these impls package private so that only tests
can change out these implementations, through test plugins.
closes#12784
No need to load catch this query since it's cheap and not reused.
If we cache it, it can cause assertions to be tripped since this
method is executed during postRecovery phase and might still run while
nodes are shutdown in tests.
This commit tries to add some infrastructure to streamline how extension
points should be strucutred. It's a simple approache with 4 implementations
for `highlighter`, `suggester`, `allocation_decider` and `shards_allocator`.
It simplifies adding new extension points and forces to register classes instead
of strings.

Please note that build doesn't fail with maven 3.2.x and it doesn't fail if mvn command is executed inside the qa/smoke-test-shaded directory. Only when the build is started from the root directory the error above can be observed.
The reason is because of the shaded version which depends on elasticsearch core.
When Maven build the module only, then elasticsearch core is not added to the dependency tree.

A fix could consist of fixing something on Maven side. Probably something changed in a recent version and introduced this "issue" but it might be not really an issue. More a fix.
There are two workarounds:
1) exclude manually elasticsearch core from shaded version in smoke-test-shaded module and add manually each lucene lib needed by elasticsearch
2) add a new `elasticsearch-lucene` (lucene) POM module which simply declares all needed lucene libs in subprojects (such as the smoke tester one).
I choose the later.
Closes#12791.
