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.
Close#6144
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.
Closes#6120
When a mapping is declared and the type is known from the uri
then the type can be skipped in the body (see #4483). However,
there was no check if the given keys actually make a valid mapping.

Percentiles are supposed to be monotonically increasing but floating-point
rounding issues can come into play and make the test fail if checks are too
strict.
