Fields of type `token_count`, `murmur3`, `_all` and `_field_names` are generated only when indexing.
If a GET requests accesses the transaction log (because no refresh
between indexing and GET request) then these fields cannot be retrieved at all.
Before the behavior was so:
`_all, _field_names`: The field was siletly ignored
`murmur3, token_count`: `NumberFormatException` because GET tried to parse the values from the source.
In addition, if these fields were not stored, the same behavior occured if the fields were
retrieved with GET after a `refresh()` because here also the source was used to get the fields.
Now, GET accepts a parameter `ignore_errors_on_generated_fields` which has
the following effect:
- Throw exception with meaningful error message explaining the problem if set to false (default)
- Ignore the field if set to true
- Always ignore the field if it was not set to stored
This changes the behavior for `_all` and `_field_names` as now an Exception is thrown if a user
tries to GET them before a `refresh()`.

Allow to set the value default to network.tcp.no_delay and network.tcp.keep_alive so they won't be set at all, since on solaris, setting tcpNoDelay can actually cause failure

CliTool is a base class for command-line interface tools (such as the plugin manager and potentially others). It supports the following:
- single or multi command tool
- help printing infrastructure (based on help files)
- consistent mechanism of parsing arguments (based on commons-cli lib)
- separation of argument parsing and command execution (for easier unit testing)
- terminal abstraction (will use System.console() when available)
A multi-bucket aggregation where multiple filters can be defined (each filter defines a bucket). The buckets will collect all the documents that match their associated filter.
This aggregation can be very useful when one wants to compare analytics between different criterias. It can also be accomplished using multiple definitions of the single filter aggregation, but here, the user will only need to define the sub-aggregations only once.
Closes#6118
Now that we have explicit support for aliases when creating indices and as part of index templates, we may remove support for aliases (only names) as part of index settings. This is partially breaking as the following calls:
curl -XPUT localhost:9200/index -d '{
"settings" : {
"aliases" : [ "alias1"]
}
}
and
curl -XPUT localhost:9200/index -d '{
"settings" : {
"index.aliases" : [ "alias1"]
}
}
were previously supported and will need to be replaced with
curl -XPUT localhost:9200/index -d '{
"aliases" : {
"alias1": {}
}
}

The histogram reduce method can run into an infinite loop if the
Rounding.nextRoundingValue value is buggy, which happened to be the case for
DayTimeZoneRoundingFloor.
DayTimeZoneRoundingFloor is fixed, and the histogram reduce method has been
changed to fail instead of running into an infinite loop in case of a buffy
nextRoundingValue impl.

Today, `copy_to` always copies a field to the current document, which is often
wrong in the case of nested documents. For example, if you have a nested field
called `n` which has a sub-field `n.source` whose content should be copied to
`target`, then the latter field should be created in the root document instead
of the nested one, since it doesn't have `n.` as a prefix. On the contrary, if
you configure the destination field to be `n.target`, then it should go to the
nested document.
Close#6701
Implements a new Exists API allowing users to do fast exists check on any matched documents for a given query.
This API should be faster then using the Count API as it will:
- early terminate the search execution once any document is found to exist
- return the response as soon as the first shard reports matched documents

Index process fails when having `_timestamp` enabled and `path` option is set.
It fails with a `TimestampParsingException[failed to parse timestamp [null]]` message.
Reproduction:
```
DELETE test
PUT test
{
"mappings": {
"test": {
"_timestamp" : {
"enabled" : "yes",
"path" : "post_date"
}
}
}
}
PUT test/test/1
{
"foo": "bar"
}
```
You can define a default value for when timestamp is not provided
within the index request or in the `_source` document.
By default, the default value is `now` which means the date the document was processed by the indexing chain.
You can disable that default value by setting `default` to `null`. It means that `timestamp` is mandatory:
```
{
"tweet" : {
"_timestamp" : {
"enabled" : true,
"default" : null
}
}
}
```
If you don't provide any timestamp value, indexation will fail.
You can also set the default value to any date respecting timestamp format:
```
{
"tweet" : {
"_timestamp" : {
"enabled" : true,
"format" : "YYYY-MM-dd",
"default" : "1970-01-01"
}
}
}
```
If you don't provide any timestamp value, indexation will fail.

This commit adds a profile that skips all validation ie.
- nocommit / tabs checking
- forbidden API checks
- license headers
It's not active by default but can easily be activated with
`mvn -Pdev` or in the `~/.m2/settings.xml`

The used -p option could result in accidentally deleting more directories
than /var/lib/elasticsearch - so this option was removed
Note: This only happens if the directories are empty, but still isnt needed.

The upgrade tests required to specify the lower and the upper version
that it should run against. This commit adds support for random picks
if either the lower or the upper or both are not specified.
This commit adds a basic full cluster restart upgrade script that tests
upgrades of elasticsearch across major version. In contrast to the BWC
tests we are running using the java test framework this test uses a python
script as well as the REST APIs to ensure upgrades across major version work and
indices are compatible.
The upgrade test starts 2 or more nodes of an old elasticserach version, indexes
a random number of documents into the running nodes and executes a full cluster restart.
After the nodes are recovered a small set of basic checks are executed to ensure all
documents are still searchable and field data can be loaded etc.
Closes#7074
This commit effectively reverts e1aa91d , as it is not needed anymore to add the original listed nodes. The cluster state local call made will in fact always return at least the local node (see #6811).
There were a couple of downsides caused by putting the original listed nodes among the connected nodes:
1) in the following retries, they weren't seen as listed nodes anymore, thus the light connect wasn't used
2) among the connected nodes some were "bad" duplicates as they are already there and don't contain all needed info for each node. This was causing serialization problems for instance given that the node version was missing on the `DiscoveryNode` object.
Closes#7067
The RetryListener was notified twice for each single failure, which caused some additional retries, but more importantly was making the client reach the maximum number of retries (number of connected nodes) too quickly, meanwhile ongoing retries which could succeed were not completed yet.
The TransportService used to throw ConnectTransportException due to throwConnectException set to true, and also notify the listener of any exception received from a separate thread through the request holder.
Simplified exception handling by just removing the throwConnectException option from the TransportService, used only in the transport client. The transport client now relies solely on the request holder to notify of failures and eventually retry.
Closes#6829
