On small hardware, the BENCH thread pool can be set to size 1. This is
problematic as it means that while a benchmark is active, there are no
threads available to service administrative tasks such as listing and
aborting. This change fixes that by executing list and abort operations
on the GENERIC thread pool.
Closes#6174
I think Chuck Norris is required to fix this at this point until we have an API
that can for instance pause a Benchmark. We basically wait for a query to be executed
and that query syncs on a latch with the test in a script :)
This commit also adds some more testing for benchmarks that run into errors.
When you have a nested document and want to sort on its fields, it's perfectly doable on regular fields but not on "generated" sub fields.
Here is a SENSE recreation:
```
DELETE /tmp
PUT /tmp
PUT /tmp/doc/_mapping
{
"properties": {
"flat": {
"type": "string",
"index": "analyzed",
"fields": {
"sub": {
"type": "string",
"index": "not_analyzed"
}
}
},
"nested": {
"type": "nested",
"properties": {
"foo": {
"type": "string",
"index": "analyzed",
"fields": {
"sub": {
"type": "string",
"index": "not_analyzed"
}
}
}
}
}
}
}
PUT /tmp/doc/1
{
"flat":"bar",
"nested":{
"foo":"bar"
}
}
```
When sorting on `flat.sub` sub field, everything is fine:
```
GET /tmp/doc/_search
{
"sort": [
{
"flat.sub": {
"order": "desc"
}
}
]
}
```
When sorting on `nested` field, everything is fine:
```
GET /tmp/doc/_search
{
"sort": [
{
"nested.foo": {
"order": "desc"
}
}
]
}
```
But when sorting on `nested.sub` field, sorting is incorrect:
```
GET /tmp/doc/_search
{
"sort": [
{
"nested.foo.sub": {
"order": "desc"
}
}
]
}
Closes#6150.
Every class using these parameters has their own member where these four
are stored. This clutters the code. Because they mostly needed together
it might make sense to group them.
The recovery API was sometimes misreporting the recovered byte
percentages of index files. This was caused by summing up total file
lengths on each file chunk transfer. It should have been summing the
lengths of each transfer request.
Closes#6113
NettyTransport's ChannelPipelineFactory uses the instance variable
serverOpenChannels in order to create sockets. However, this instance variable
is set to null when stoping the netty transport, so if the transport tries to
stop and to initialize a socket at the same time you might hit the following
NullPointerException:

This fix ensures that the ChannelPipelineFactory always uses the channels that
have been used upon start, even if a stop request is issued concurrently.

Our improvements to t-digest have been pushed upstream and t-digest also got
some additional nice improvements around memory usage and speedups of quantile
estimation. So it makes sense to use it as a dependency now.
This also allows to remove the test dependency on Apache Mahout.
Close#6142
It's dangerous to expose SerialMergeScheduler as an option: since it only allows one merge at a time, it can easily cause merging to fall behind.
