By default we won't allow rebalance operation if no all shards are active.
if this is the case we don't need to worry about costly rebalance calculations at all.
to enable download servers to send the correct plugin version for the
node that is installing it this PR sends the current version as a header
to the server.
In case a HTTP client connects to the transport protocol and issues a
HTTP method followed by a space, we can just try to be smart and return
a string back to the client to point the user to the fact that the wrong
port has been used.

This commit adds the current total number of translog operations to the recovery reporting API. We also expose the recovered / total percentage:
```
"translog": {
"recovered": 536,
"total": 986,
"percent": "54.3%",
"total_time": "2ms",
"total_time_in_millis": 2
},
```

The filter from an indexed alias is as if you would filter on the metadata of a percolator query, but then the filter is defined in the index alias instead of the percolate request.
Closes#6241
The behaviour is better in the case someone has multiple levels of nested object fields defined in the mapping and like to define a single inner_hits definition that is two or more levels deep.
If someone wants inner hits on a nested field that is 2 levels deep the following would need to be defined:
```
{
...
"inner_hits" : {
"path" : {
"level1" : {
"inner_hits" : {
"path" : {
"level2" : {
"query" : { .... }
}
}
}
}
}
}
}
```
With this change the above can be defined as:
```
{
...
"inner_hits" : {
"path" : {
"level1.level2" : {
"query" : { .... }
}
}
}
}
```

The BWC tests also run against a snapshot build of previous release branches. Upon a failure it's important to know what commit exactly was used.

PageCacheRecycler was mistakenly using the maximum number of items per page
instead of the byte size of a page. This could result in higher memory usage
than configured.

This solves a problem in the time zone rounding classes where time dates that
fall into a DST gap will cause joda time library to throw an exception.
Changing the conversion methods 'strict' option to false prevents this.

To support real time gets, the engine keeps an in-memory map of recently index docs and their location in the translog. This is needed until documents become visible in Lucene. With 1.3.0, we have improved this map and made tightly integrated with refresh cycles in Lucene in order to keep the memory signature to a bare minimum. On top of that, if the version map grows above a 25% of the index buffer size, we proactively refresh in order to be able to trim the version map back to 0 (see #6363) . In the same release, we have fixed an issue where an update to the indexing buffer could result in an unwanted exception during recovery (#6667) . We solved this by waiting with updating the size of the index buffer until the shard was fully recovered. Sadly this two together can have a negative impact on the speed of translog recovery.
During the second phase of recovery we replay all operations that happened on the shard during the first phase of copying files. In parallel we start indexing new documents into the new created shard. At some point (phase 3 in the recovery), the translog replay starts to send operation which have already been indexed into the shard. The version map is crucial in being able to quickly detect this and skip the replayed operations, without hitting lucene. Sadly #6667 (only updating the index memory buffer once shard is started) means that a shard is using the default 64MB for it's index buffer, and thus only 16MB (25%) for the version map. This much less then the default index buffer size 10% of machine memory (shared between shards).
Since we don't flush anymore when updating the memory buffer, we can remove #6667 and update recovering shards as well. Also, we make the version map max size configurable, with the same default of 25% of the current index buffer.
Closes#10046
The analysis chain should be used instead of relying on this, as it is
confusing when dealing with different per-field analysers.
The `locale` option was only used for `lowercase_expanded_terms`, which,
once removed, is no longer needed, so it was removed as well.

The file scripts cache key should include the language of the script to prevent conflicts between scripts with same name but different extension (hence lang). Note that script engines can register multiple acronyms that may be used as lang at execution time (e.g. javascript and js are synonyms). We then need to make sure that the same script gets loaded no matter which of the acronyms is used at execution time. The problem didn't exist before this change ad the lang was simply ignored, while now we take it into account.
This change has also some positive effect on inline scripts caching. Up until now, the same script referred to with different acronyms would be compiled and cached multiple times, once per acronym. After this change every script gets compiled and cached only once, as we chose internally the acronym used as part of the cache key, no matter which one the user provides.
Closes#10033
Remove the settings around dangling indices, such as no import and timeout for deletion, we always want to import dangling indices for safety, and we should not allow to change the behavior. This also cleans up the code quite a bit.
closes#10016
we want to make sure the recovery finished all the way to post recovery. Current check, validating the shard is either in POST_RECOVERY or STARTED is not good because the shard could be also closed if things go fast enough (like in our tests). The assertion is changed to check the shard is not left in CREATED or RECOVERING.
Closes#10028
- Added NAME constants for each script language, avoiding to repeat the same strings all over the place.
- Simplified `compile` method signatures by removing a couple of variants. Note that all of these signatures are going to change again with #6418 as in order to compile/execute a script the caller will need to specify which operation is attempting to execute the script, info that will be provided as an additional mandatory argument.
- Removed double call to ScriptService#verifyDynamicScripting for every indexed or dynamic script.
- Decreased ScriptService inner classes visibility to private (CacheKey, IndexedScript, ApplySettings)
- Moved ScriptService inner classes to the bottom of the class, I think it makes it more readable.
- Resolved some compiler warnings
Closes#9992
The tribe node, at startup, sets up the tribe clients that will join their corresponding tribes. All of the tribe.* settings are properly forwarded to the corresponding tribe client. System properties and global configuration settings must not be forwarded to the tribe client though or they will end up overriding per tribe settings with same name causing issues.
For instance if you set the transport.tcp.port to some defined value for the tribe node, via system property or configuration file, that same value must not be forwarded to the tribe clients, otherwise they will try and use the same port, which will be already occupied by the tribe node itself, resulting in startup failed. Same for cluster.name, which will cause the tribe clients not to join their tribes.
