This commit addresses a time unit conversion bug in calculating the age
of a PrioritizedRunnable. The issue was an incorrect conversion from
nanoseconds to milliseconds as instead the conversion was to
microseconds. This leads to the timeInQueue metric for pending tasks to
be off by three orders of magnitude.
* Folded IngestModule into NodeModule
* Renamed IngestBootstrapper to IngestService
* Let NodeService construct IngestService and removed the Guice annotations
* Let IngestService implement Closable
We have a performance bug that if a filter aggregation is below a terms
aggregation that has a cardinality of 1000, we will call Query.createWeight
1000 times as well. However, Query.createWeight can be a costly operation.
For instance in the case of a TermQuery it will seek the term in every
segment. Instead, we should create the Weight once, and then get as many
iterators as we need from this Weight.
I found this problem while trying to diagnose a performance regression while
upgrading from 1.7 to 2.1[1]. While the problem was not introduced in 2.x, the
fact that 1.7 cached very aggressively had hidden this problem, since you don't
need to seek the term anymore on a cached TermFilter.
Doing things once for every aggregator is not easy with the current API but
I discussed this with Colin and Aggregator factories will need to get an init
method for different reasons, where we will be able to put these steps that
need to be performed only once, no matter haw many aggregators need to be
created.

With this commit we do not check only if an endpoint is up but
we also check that the cluster status is green. Previously,
builds sporadically failed to pass this condition.
If an operating system reports -1 for the total bytes of a filesystem
path, we should ignore it when capturing the least and most available
statistics.

This commit removes the timeout retry mechanism from ShardStateAction
allowing it to instead be handled by the general master channel retry
mechanism. The idea is that if there is a network issue, the master will
miss a ping timeout causing the channel to be closed which will expose
itself via a NodeDisconnectedException. At this point, we can just wait
for a new master and retry, as with any other master channel exception.
This commit moves the handling of channel failures when failing a shard
to o.e.c.a.s.ShardStateAction. This means that shard failure requests
that timeout or occur when there is no master or the master leaves after
the request is sent will now be retried from here. The listener for a
shard failed request will now only be notified upon successful
completion of the shard failed request, or when a catastrophic
non-channel failure occurs.
This commit adds a simulation of the master leaving after a shard
failure request has been sent. In this case, after a new cluster state
is published (simulating a new master having been elected), the request
to fail the shard should be retried.
This commit handles the situation when we are failing a shard and either
no master is known, or the known master left while failing the shard. We
handle this situation by waiting for a new master to be reelected, and
then sending the shard failed request to the new master.
To main concern with the dedicated ingest TP is that there are already many TPs and in the case with beefy nodes we would many more threads. In the case ingest isn't used the all these threads are just idle.
Adding serialization capabilities to RescoreBuilder and make
all QueryRescorer implement NamedWritable, also requiring
all implementations of RescoreBuilder.Rescorer to implement
equals() and hashCode.
In addition, the current rescore mode enumeration is pulled out to a
separate class to make sharing of constants easier between
the query builders XContent rendering coder and the parser.
Using a single azure account is now rejected.
This commit fixes this issue and adds a test for it.
This regression was introduced with #13779. Hopefully no elasticsearch version has been released since then.
Needs to be merged in 2.2, 2.x and master branches.
This change affects get alias, get aliases as well as cat aliases. They all return closed indices too by default. get alias and get aliases also allow to return open indices only through the `expand_wildcards` option (set it to `open`).
Closes#14982
This undocumented setting was mainly used for testing and a safety net for
a new flushOnClose feature back in 1.x. We can now safely remove this setting.
The test usage now uses a mock plugin setting to achive the same.
