If a path to the test classes contains spaces Hunspell tests failed due
to URL encoded paths. This happens on CI builds if you give the build
a name containing a space. This is fixed by first converting to a URI
and created a File object from the URI directly.
The fact that Maven and Eclipse share the same build directories can trigger
race conditions when both are trying to build at the same time, eg. if you run
`mvn clean test` while Eclipse is up and running: Eclipse will notice that some
class files are missing and start compiling in parallel with Maven.
In a special case if allocations from the "heaviest" to the "lighter" nodes is not possible
due to some allocation decider restrictions like zone awareness. if one zone has for instance
less nodes than another zone so one zone is horribly overloaded from a balanced perspective but we
can't move to the "lighter" shards since otherwise the zone would go over capacity.
Closes#3580
When recovery of a shard fails on a node, the node sends notification to the master with information about the failure. During the period between the shard failure and the time when notification about the failure reaches the master, any changes in shard allocations can trigger the node with the failed shard to allocate this shard again. This allocation (especially if successful) creates a ripple effect of the shard going through failure/started states in order to match the delayed states processed by master. Under certain condition, a node involved in this process might generate warning messages: "marked shard as started, but shard has not been created, mark shard as failed".
This fix makes sure that nodes keep track of failed shard allocations and will not try to allocate such shards repeatedly while waiting for the failure notification to be processed by master.
Shard relocation caused queries to fail in the fetch phase either with a
`AlreadyClosedException` or a `SearchContextMissingException`.
This was caused by the `SearchService` releasing the `SearchContext`s via the
superfluous call of `releaseContextsForShard()` when the
This commit allows for configuring the sort order of missing values in BytesRef
comparators (used for strings) with the following options:
- _first: missing values will appear in the first positions,
- _last: missing values will appear in the last positions (default),
- <any value>: documents with missing sort value will use the given value when
sorting.
Since the default is _last, sorting by string value will have a different
behavior than in previous versions of elasticsearch which used to insert missing
value in the first positions when sorting in ascending order.
Implementation notes:
- Nested sorting is supported through the implementation of
NestedWrappableComparator,
- BytesRefValComparator was mostly broken since no field data implementation
was using it, it is now tested through NoOrdinalsStringFieldDataTests,
- Specialized BytesRefOrdValComparators have been removed now that the ordinals
rely on packed arrays instead of raw arrays,
- Field data tests hierarchy has been changed so that the numeric tests don't
inherit from the string tests anymore,
- When _first or _last is used, internally the comparators are told to use
null or BytesRefFieldComparatorSource.MAX_TERM to replace missing values
(depending on the sort order),
- BytesRefValComparator just replaces missing values with the provided value
and uses them for comparisons,
- BytesRefOrdValComparator multiplies ordinals by 4 so that it can find
ordinals for the missing value and the bottom value which are directly
comparable with the segment ordinals. For example, if the segment values and
ordinals are (a,1) and (b,2), they will be stored internally as (a,4) and
(b,8) and if the missing value is 'ab', it will be assigned 6 as an ordinal,
since it is between 'a' and 'b'. Then if the bottom value is 'abc', it will
be assigned 7 as an ordinal since if it between 'ab' and 'b'.

count_percolate -> count
percolate_existing_doc -> percolate
count_percolate_existing_doc -> count
If header contains `id` field, then it will automatically be percolation an existing document.
The highlighter in the percolate api highlights snippets in the document being percolated. If highlighting is enabled then foreach matching query, highlight snippets will be generated.
All highlight options that are supported via the search api are also supported in the percolate api, since the percolate api embeds the same highlighter infrastructure as the search api.
The `size` option is a required option if highlighting is specified in the percolate api, other than that the `highlight`request part can just be placed in the percolate api request body.
Closes#3574
- improve the test to be more re-creatable
- have tests for various number of replica counts, to check if failures are caused by searching on replicas that might not have been refreshed yet
- improve test to test explicit index creation, and index creation caused by index operation
- have an initial search go to _primary, to check if failure fails when searching on replica because it missed a refresh

This feature allows to retrieve [term vectors](https://github.com/elasticsearch/elasticsearch/issues/3114) for a list of documents. The json request has exactly the same [format](https://github.com/elasticsearch/elasticsearch/issues/3484) as the ```_termvectors``` endpoint
It use it, call
```
curl -XGET 'http://localhost:9200/index/type/_mtermvectors' -d '{
"fields": [
"field1",
"field2",
...
],
"ids": [
"docId1",
"docId2",
...
],
"offsets": false|true,
"payloads": false|true,
"positions": false|true,
"term_statistics": false|true,
"field_statistics": false|true
}'
```
The return format is an array, each entry of which conatins the term vector response for one document:
```
{
"docs": [
{
"_index": "index",
"_type": "type",
"_id": "docId1",
"_version": 1,
"exists": true,
"term_vectors": {
...
}
},
{
"_index": "index",
"_type": "type",
"_id": "docId2",
"_version": 1,
"exists": true,
"term_vectors": {
...
}
}
]
}
```
Note that, like term vectors, the mult term vectors request will silenty skip over documents that have no term vectors stored in the index and will simply return an empty response in this case.
